Toilet Replacement (like-for-like)

Handis toilet replacement is the same-day swap on the existing closet flange and the existing supply rough-in — round-front, elongated, comfort-height, or one-piece toilet configurations — from $450 for a clean swap on a sound flange to $950 for a swap that needs a brass-flange repair or a flange-extender set under the bowl. The 1995 toilet that wobbles at the front bolts every time someone leans forward. The original-to-the-house toilet that uses 5 gallons per flush and has been failing the flapper for three years. The comfort-height upgrade the homeowner has been planning since they turned 60. Two to three hours per toilet on a clean flange. New wax ring, new closet bolts, new water supply line, full flush and leak test across multiple cycles before the visit closes. Honest scope on the flange — if the flange is cracked below the rim, sunken below the finish floor, or sitting on rotted subfloor, that work routes to a licensed Washington L&I plumber and is named on the quote before the new toilet ships.

What Does a Like-for-Like Toilet Replacement Include?

A like-for-like toilet replacement is the same-day toilet swap on an existing closet flange and existing supply rough-in — covering water shut-off at the toilet supply, removal of the existing toilet (water bailed and tank drained, then tank-and-bowl lifted in one piece for standard residential weights), inspection of the closet flange and wax ring seat, set of the new toilet with a new wax ring (or wax-free seal where the new toilet specifies it), new closet bolts, new supply line, and a flush and leak test across multiple cycles. Handis covers same-day installs from $450 on a clean flange to $950 with a brass-flange repair or a flange-extender set. Most installs finish in 2 to 3 hours.

Round-Front Toilet (Standard Footprint)

The compact toilet footprint — 16.5 to 17 inch bowl rim length, dominant in older Seattle bathrooms (1950s-1990s construction) and smaller half-baths. Replacement on the existing flange and existing supply rough-in. Two-piece (separate tank and bowl) or one-piece configurations available. From $450 labor.

Elongated Toilet (Standard Footprint)

The larger toilet bowl — 18 to 18.5 inch bowl rim length, dominant in newer construction and master baths where the floor space allows. Many homeowners upgrade round-front to elongated when replacing. Same flange position; bowl footprint extends slightly forward. From $500 labor.

Comfort-Height Toilet (ADA-Adjacent)

The taller toilet — 17 to 19 inch seat height (compared to standard 14 to 15 inch), easier to sit down on and stand up from for older adults or anyone with joint sensitivity. Comfort-height is now the dominant new-install on residential remodels in Seattle. Same flange position; tank often sits taller. From $500 labor.

One-Piece Toilet (Tank and Bowl Integrated)

The integrated tank-and-bowl unit — cleaner lines, no caulk seam between tank and bowl, easier to clean. Heavier as a single lift (90 to 110 pounds vs 50 to 70 pounds for two-piece) so the tech sets it with care. From $550 labor.

Wax-Ring Seal, New Closet Bolts, New Supply Line as Standard

Every toilet replacement includes a new wax ring sized to the toilet horn (or a wax-free seal like a Korky Universal where the new toilet specifies it), new brass or stainless steel closet bolts (the old bolts often have corroded heads from sitting in a wet zone for years), and a new braided stainless steel water supply line. The bowl gets caulked at the base with 100 percent silicone (a small drain gap at the rear is left for any future leak to surface where it can be seen).

Toilet Replacement Pricing

Final pricing is labor plus any condition-driven adders. Toilet kit cost depends on brand and configuration (owner-supplied is fine). A cracked or sunken closet flange that needs in-wall drain repair routes to a licensed Washington L&I plumber as a transparent line-item adder. Request a free estimate for an accurate quote.

Why Handis for Toilet Replacements

Why Handis for Toilet Replacements

Most toilet replacements run clean — the old toilet comes out in one lift, the flange underneath is in good shape, the new wax ring sets, the new toilet drops onto the bolts and never moves again. The few that surface a flange problem (cracked PVC from 1990s construction, a flange that has sunken below the finish floor after years of subfloor compression, a flange sitting on a soft patch of subfloor that has been weeping at the wax ring for who knows how long) are the ones that justify the inspection step we run before the new toilet ever ships. Replacing a wobbly toilet without fixing the flange underneath just buys another wobbly toilet six months from now. We tell the homeowner what is under there before we ask them to sign for the new install — and the in-wall portion routes to the licensed plumber as a separate line on the quote.

Inspect the closet flange before the new toilet sets

The closet flange is the brass or PVC ring that the toilet bolts to and the wax ring seals against. A wobbly toilet, a stained base, soft subfloor felt underfoot — every one of those is a flange problem until proven otherwise. We pull the old toilet, photograph the flange, and tell the homeowner what we see before the new toilet comes out of the box. A sound flange means a clean swap. A cracked or sunken flange means a handyman flange extender ($120 add-on) or a licensed plumber for a brass-flange replacement ($250 typical plumber sub, passed through transparent).

New wax ring, new bolts, new supply line on every job

Every toilet replacement gets a fresh wax ring sized to the new toilet's horn (or a wax-free seal like a Korky Universal where the new toilet specifies it), new brass or stainless steel closet bolts (the old bolts usually have corroded heads from sitting in a wet zone for 15 to 30 years), and a new braided stainless steel water supply line. None of those parts get carried forward to a fresh install — they are inexpensive, they fail in known ways, and they belong in the swap scope.

Set the toilet straight down, never rock it side to side

A wax ring seals only when the toilet sets straight down onto the flange and stays there during bolt tightening. Rocking the bowl side-to-side to position the bolts deforms the wax and breaks the seal before the toilet is even tightened. The result is a leak at the base that surfaces weeks later when the wax cures fully. We set the toilet straight down once, position-check it before any rocking, and tighten in alternating quarter-turns to spec.

Multi-cycle flush test before sign-off

Multi-cycle flush test (at least three flushes) checks for three independent leak modes — tank-to-bowl leaks at the gasket, base leaks at the wax ring, and supply-side leaks at the fill-valve connection. Anything that drips, weeps, or stays damp gets diagnosed and re-sealed before the visit closes. The bowl base gets caulked with 100 percent silicone with a small rear drain gap left so any future leak surfaces where you can see it.

Honest plumber handoff on the in-wall scope

Anything inside the wall — a cracked closet bend below the flange, a drain pipe that needs to be relocated, a flange that has dropped because the cast-iron drain stack underneath has corroded — routes to a licensed Washington L&I plumber. We name the sub scope on the quote with the typical sub-fee range so the homeowner sees the all-in number before the install is booked.

Insured, background-checked, 30-day workmanship guarantee

Every Handis tech carries liability insurance and has cleared a background screening. 30-day workmanship guarantee — if the toilet rocks, leaks at the base, the supply line backs out, or the tank gasket weeps within 30 days because of our install, we come back and fix it at no extra charge. The guarantee covers our install scope — it does not cover the toilet's internal valves or flapper failing months later (known wear parts on their own lifecycle), a flange that fails downstream from our work because the in-wall drain was already compromised, or hairline cracks in the toilet from someone sitting on it at an angle.

Estimate

Send us a phone photo of the existing toilet base from a few angles and note any visible wobble, staining at the base, or soft subfloor underfoot. Tell us the new toilet (round-front, elongated, comfort-height, one-piece, brand and model if you have picked) and how many toilets are in scope. We send a written quote with any plumber-sub scope called out separately when applicable.

FAQ

Frequently Asked Questions

Common questions about like-for-like toilet replacements.

How much does a toilet replacement cost?
Labor starts at $450 for a round-front two-piece toilet on a clean flange and clean supply rough-in. Elongated and comfort-height are $500. One-piece toilets with integrated tank-and-bowl are $550. Common add-ons — $120 for a plastic flange extender when the finish floor has built up above the flange rim, $250 plumber sub for a brass-flange replacement when the existing PVC flange is cracked or sunken, $200 for a small subfloor patch under the flange when the rot is contained. Two toilets in one visit bundle at $800. If the work crosses into in-wall drain repair, the licensed-plumber sub fee passes through as a separate line item on the quote. Owner-supplied toilet is fine; we can also source from Toto, Kohler, American Standard, and Glacier Bay lines.
How long does a toilet replacement take?
A standard like-for-like swap on a clean flange is 2 to 3 hours including water shut-off, removal, flange inspection, new wax ring set, install, supply line connect, multi-cycle flush test, and base caulk. A swap with a flange extender adds about 30 minutes. A swap with a plumber-sub brass-flange replacement adds the plumber portion to the visit (usually 1 to 2 hours of plumber on-site). A two-toilet bundle is 3.5 to 4.5 hours total. Bathroom is usable immediately after the install — the silicone base caulk skins in 30 minutes.
Do you supply the toilet, or do I?
Either way. Owner-supplied is fine — name the brand, model, and configuration (round-front, elongated, comfort-height, one-piece, two-piece) on the booking call so we can confirm fit and have any specific parts on the truck. We can also source from common Seattle brand lines (Toto Drake / UltraMax, Kohler Wellworth / Highline, American Standard Champion, Glacier Bay). The lead time is yours on owner-supplied and ours on Handis-sourced.
What if the closet flange is cracked or sunken?
Two paths depending on the failure. Path one (handyman scope) — the flange has dropped slightly because the finish floor has built up above it (a common situation after a tile or LVP install), and a plastic flange extender brings the seat up to the right height. $120 add-on, no plumber needed. Path two (plumber scope) — the PVC or cast iron flange itself is cracked at the bolt slot, sunken because the drain pipe underneath has settled, or the closet bend underneath is damaged. That routes to a licensed Washington L&I plumber for a brass-flange replacement ($250 typical sub fee) or a more involved in-wall drain repair. We photograph the flange when we lift the old toilet and tell the homeowner what we see before the new toilet sets.
What if the subfloor under the toilet is soft?
Soft subfloor under the flange usually means a slow leak has been weeping at the wax ring for months or years. Two paths. Small patch (1 to 2 square feet of rot contained around the flange) is handyman scope — $200 to cut out the rot, install a new plywood patch, and seal before the new flange and toilet set. Larger rot, or rot that extends to the joist underneath, routes to the plumber sub for the in-wall drain work and a Handis carpenter for the structural patch. We never set a new toilet on rotted subfloor and call it done.
Should I upgrade to comfort-height while I am replacing?
Most homeowners we replace toilets for choose comfort-height now (17 to 19 inch seat height vs the standard 14 to 15 inch). Easier to sit down and stand up from for adults over 50, anyone with knee or hip sensitivity, and anyone planning to age in place. The tank is taller so the visible profile is bigger, which some owners do not love in a powder room. The footprint and the flange position are the same as standard-height in most modern designs. We confirm the model fit on the booking call.
How is the new toilet sealed to the floor?
A new wax ring sized to the toilet horn (or a wax-free seal where the new toilet specifies it) creates the watertight seal at the flange. The wax compresses as the toilet sets and the closet bolts tighten — that is the primary water seal. We then caulk the base with 100 percent silicone, leaving a small rear drain gap so any future leak surfaces where it can be seen (rather than getting trapped under the bowl and rotting the subfloor invisibly). This is the standard residential install procedure and matches Washington plumbing-code best practice.
Will my new toilet match the existing flooring or do I need to refinish?
The toilet footprint usually matches or extends slightly past the old footprint — a round-front to elongated upgrade adds about an inch and a half forward, a comfort-height upgrade does not change footprint. A small visible ring or staining where the old toilet sat is common on tile or LVP floors and usually cleans up with a magic-eraser pad. If the ring is heavier (a yellowed circle on linoleum, a wax-bleed stain on tile) it may not fully clean up — we say so on the visit. Full flooring refresh is outside this scope.
Can I replace two or more toilets in one visit?
Yes — and that is the cheapest way to book it. A two-toilet bundle is $800 for two toilets in one visit, one trip charge, one cleanup. Three-toilet bundles run roughly $1,150. The tech sequences the work so the second toilet's wax ring sets while the first is on its flush test. Both bathrooms are usable by end of visit.
What if the existing supply line is corroded or cracked?
Every toilet replacement gets a new braided stainless steel water supply line as standard scope (no add-on). The old supply line — usually a chrome flex or a corroded compression-fit copper — comes off and stays off. The toilet stop (the small angle stop at the wall behind the toilet) is checked at the same time. If the stop is seized or weeping, we replace it on a threaded connection ($80 add-on) or route to the plumber sub if it is on a compression or soldered connection that needs in-wall work.
Is the work guaranteed?
Yes. 30-day workmanship guarantee on every toilet replacement — if the toilet rocks, leaks at the wax-ring base, the supply line backs out at the connection, or the tank gasket weeps within 30 days because of our install, we come back and fix it at no extra charge. The guarantee covers our install scope — it does not cover the toilet's internal fill valve or flapper failing months later (known wear parts on their own lifecycle), a flange that fails downstream from our work because the in-wall drain was already compromised, or hairline cracks in the porcelain from someone sitting on the bowl at an angle or dropping something on it. The licensed-plumber sub portion (when triggered) carries its own L&I-trade workmanship guarantee, also named on the quote.
