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).
How a Like-for-Like Toilet Replacement Works
Six sequential steps from water shut-off to multi-cycle flush test — the actual sequence on every like-for-like toilet replacement.
Confirm Flange Condition and Toilet from Booking-Call Photos
Phone photo of the existing toilet base from a few angles plus a description of any wobble or staining at the base, sent on the booking call. Flange condition cannot be confirmed without removing the toilet, but visible signs (a rocking toilet, staining at the base, soft subfloor noticeable underfoot) flag the likelihood of a flange repair before the new toilet ships.
Shut Off Water, Drain the Tank, Lift the Old Toilet
Supply shut off at the toilet stop. Tank drained by flushing while holding the handle down. Residual water in tank and bowl bailed out and sponged dry to prevent spills during the lift. Closet bolts removed. Tank-and-bowl lifted in one piece for standard residential weights; two-piece toilets lifted as two parts if the tech is working alone.
Inspect the Closet Flange and the Wax-Ring Seat
Flange inspected for cracks (a common failure on PVC flanges from 1990s-era construction), sunken position (a flange below the finish floor needs an extender), and structural integrity of the subfloor underneath. A sound flange — proceed. A cracked or sunken flange — stop, photograph, quote the repair scope (handyman flange extender or plumber-sub brass-flange replacement) before the new toilet sets.
Set the New Wax Ring, Install New Closet Bolts
New wax ring sized to the toilet horn (standard, jumbo, or wax-free seal where the new toilet specifies it). New brass or stainless steel closet bolts seated in the flange slots. Old corroded bolts go to metal recycling.
Set the New Toilet, Tighten Closet Bolts to Spec
New toilet lifted and lowered straight down onto the wax ring (no rocking the bowl side-to-side during the set, which deforms the wax and breaks the seal before the toilet is even tightened). Bolts tightened in alternating quarter-turns until the bowl is firm to the floor — never over-cranked (over-cranked closet bolts crack the porcelain at the bolt hole). Tank assembled to bowl with new tank bolts and tank gasket.
Connect Supply, Pressurize, Multi-Cycle Flush Test, Final Caulk
New braided stainless steel supply line connected from the toilet stop to the tank fill valve. Water back on. Fill valve adjusted to the manufacturer's water-line spec. Multi-cycle flush test (at least three flushes) checks for tank-to-bowl leaks at the gasket, base leaks at the wax ring, and supply leaks at the fill-valve connection. Base caulked with 100 percent silicone, small rear drain gap left so any future leak surfaces 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.
Send phone photos of the existing toilet base from a few angles and note any wobble — we will quote the swap before booking.
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.
Customer Reviews
Toilet replacement reviews from real Handis customers.
1995 round-front toilet in our master bath wobbled forever and used way too much water per flush. Handis swapped it for a Toto comfort-height elongated, two-piece. Flange was in good shape, clean wax ring set, all done in two hours. The water bill dropped noticeably the next month.
Toilet in the powder room of our 1924 bungalow had been wobbling for years. Tech pulled it, found the original lead closet flange had a hairline crack at the bolt slot. Called the plumber sub the same day, brass flange replaced, then the new Kohler set. Sub fee was on a separate line item just like they explained on the booking call.
Two toilets — master and hall bath — done in one visit. Both round-front to elongated upgrades. The tech sequenced them so the master cured while he worked on the hall. Three and a half hours total, one trip, one cleanup. Both flushes solid on the multi-cycle test.
We upgraded to a one-piece comfort-height in the master bath for my mother-in-law moving in. Tech set the heavier one-piece carefully, no rocking, and even the closet bolts went on at the right torque (he showed me the wrench setting). Toilet is solid as a rock and looks built-in.
Tile floor had been built up over the years and the flange sat about half an inch below the new finish floor. Tech installed a plastic flange extender to bring the seat up to the right level, set the new toilet on top with a jumbo wax ring. No need to open the floor, no plumber call. Standard scope explained clearly.
