Hot Tub Privacy Enclosure
The hot tub on the back patio that has been a tarp-covered eyesore since the new neighbors built a two-story addition with a clear sight-line into it. The Caldera or Hot Spring tub from 2018 that the homeowner used twice a month for the first year and almost never since because the cold wind funnels between two houses and hits the face during the soak. The Sundance tub the homeowner has been meaning to put a privacy screen around for three winters and has not got to. Hot tub privacy enclosure is the carpentry build that turns the exposed hot tub into a destination the homeowner actually uses year-round — cedar slat privacy screens on the sides where neighbors see in, a pergola overhead for partial rain coverage and to define the space, an optional decking surround that steps up around the tub for easy entry. Pure carpentry — the hot tub electrical (240V GFCI to NEC 680) is already in place from the original tub install. From $2,000 for a three-sided cedar slat screen around an existing tub to $6,000 for a full pergola with decking surround and cedar privacy on all sides. Two to four working days for most projects. The Pacific Northwest hot tub is genuinely useful year-round; the privacy enclosure solves the exposure problem that kills the use.

What Hot Tub Privacy Enclosure Covers
Hot tub privacy enclosure is the carpentry build around an existing or new hot tub — privacy screens, pergola overhead, decking surround, the carpentry detail that turns an exposed tub into a destination the homeowner uses year-round. Pure carpentry. The hot tub electrical (240V GFCI to NEC 680 from a licensed Washington L&I electrician) is already in place from the original tub install — if the tub is new and electrical is needed, we coordinate that separately with the licensed electrician but it is not part of this scope. The pad under the tub stays as-is (concrete, pavers, or deck surface depending on the original install).
Cedar Slat Privacy Screens
The core of every privacy enclosure. Cedar slat panels framed between cedar posts, slat spacing chosen for the privacy detail desired (3/4-inch gap for full privacy with airflow, 1/4-inch gap for screen-only privacy with maximum airflow). Typically one to three sides depending on the property — the side facing the house often stays open for the view from inside, the sides facing neighbors get full coverage, the side away from any neighbor often gets partial coverage or stays open for a view. Post heights set tall enough to block the sight-line from the neighbor's second-story window (the calculation done at the estimate visit from the actual sight angles).
Pergola Overhead
Optional but recommended for Pacific Northwest year-round use. A cedar pergola framed with 6x6 cedar posts and 4x6 cedar rafters, rafters spaced 3 inches apart for maximum rain coverage or 6 inches apart for more open-sky feel. The 3-inch-spaced rafter pattern blocks 70 percent of vertical rain — enough that face-rain during a soak is reduced to a fine mist. Adds $1,500 to $2,000 depending on size and complexity. Defines the tub space visually so the tub reads as a destination rather than a piece of equipment on the patio.
Decking Surround with Step-Up
Optional but common on installs where the tub sits low on a concrete pad and the homeowner wants the no-step or single-step entry. A cedar decking platform built around the tub at the tub-rim height with a built-in step or steps to grade. Makes tub entry easier (no climbing over the tub rim from grade), creates a destination feel, and provides a wet zone of decking around the tub for water shed during entry and exit. Adds $1,500 to $2,500 depending on the size. Decking can be cedar, pressure-treated, or composite (matched to any existing decking on the property).
Optional Cedar Bench, Towel Hook Strip, Hose-Reel Cabinet
Small details that turn the privacy enclosure into a usable space — a built-in cedar bench for towels and seating before and after the soak, a slat-and-hook towel strip on the inside wall of the privacy screen, a small cedar cabinet for the chemical and hose storage. Each adds $400 to $800 depending on scope. Optional but common requests on premium builds.
How the Hot Tub Privacy Enclosure Install Works
Six sequential phases from site review to closeout — the actual working sequence we run on every hot tub privacy enclosure install, with the existing tub left in place (we work around it) and the electrical untouched.
Site Review + Sight-Line Mapping
Estimate visit walks the back patio and the hot tub location, identifies the neighbor sight-lines that need to be blocked (typically a second-story window across the property line, a kitchen window from the house next door, a deck on the property behind), maps the post heights and slat spacing needed to block those specific sight-lines, confirms which sides of the tub need privacy and which sides can stay open for views from the house.
Post Layout + Foundation Confirmation
Post locations marked around the existing tub at the privacy-screen perimeter (typically 18 to 24 inches outside the tub edge for clearance). For posts on an existing concrete pad, the bases are stainless anchor-bolted to the concrete. For posts on a deck, through-bolted to the framing with stainless 1/2-inch carriage bolts and washers into solid rim-joist blocking (added if not present). For posts on grade, concrete footings dug below the local frost line (typically 18 inches in the Seattle area) and post bases set in the concrete.
Post Setting + Pergola Frame (Day 1-2)
Cedar 6x6 posts set, plumbed, and fastened (anchor-bolted to concrete, through-bolted to framing, or concrete-set on grade depending on the substrate). For pergola installs, 4x6 cedar headers and rafters cut and notched for the pergola structure, lifted and fastened to the posts. Pergola rafters spaced 3 inches apart for maximum rain coverage or 6 inches for more open-sky feel depending on the homeowner's preference.
Cedar Slat Privacy Screen Install (Day 2-3)
Cedar 1x4 or 1x6 slats cut to length, fastened to horizontal cedar rails between posts at the slat spacing specified (typically 1/2 to 3/4-inch gap for full privacy with airflow, 1/4-inch gap for screen-only privacy with maximum airflow). Slats run vertically (the more common modern look) or horizontally (the more traditional look) at the homeowner's choice. All fasteners stainless to avoid staining the cedar over time.
Decking Surround + Step-Up (Optional, Day 3-4)
For installs that include a decking surround, cedar (or PT or composite to match existing) decking platform framed around the tub at the tub-rim height. Built-in step (or steps depending on the height) from grade to deck. Tub access opening sized for the tub cover lift and the tub maintenance access. All decking stainless-fastened. Decking gets a quick check for level and any squeak.
Bench, Towel Strip, Cabinet, Finish (Day 4)
Any optional details installed — built-in cedar bench at one side, towel-hook slat strip on an inside privacy panel, small cedar cabinet for chemical and hose storage. Finish coordination — cedar can be left bare to silver naturally (the most popular PNW choice), oiled with Penofin or TWP for the warm cedar tone retention, or pre-finished if the homeowner has a specific stain in mind. Site cleaned, debris hauled, and the closeout walk-through with the homeowner.
Hot Tub Privacy Enclosure Pricing
Final pricing depends on the scope (three-sided screen vs full pergola vs decking surround vs all of it), the post foundation type (anchor-bolt to existing concrete, through-bolt to existing deck, or concrete-set on grade), the cedar slat spacing and post height, and the optional details (bench, towel strip, cabinet). The hot tub electrical is not part of this scope (already in place or coordinated separately with a licensed Washington L&I electrician).

Why Seattle Homeowners Book Handis for Hot Tub Enclosures
The hot tub on the back patio is a $6,000 to $20,000 asset the homeowner uses twice a month at best because the tub is exposed — the neighbors see in, the cold wind funnels through, the rain hits the face during a soak, the tub feels like a piece of equipment on the patio rather than a destination. A $2,000 to $6,000 cedar privacy enclosure changes the use pattern entirely. The same homeowner who used the tub twice a month uses it three times a week once it has cedar privacy screens and a pergola overhead. The tub becomes the spot for the wet-bike-ride decompression, the 38-degree drizzly January Saturday soak, the post-trail-run reset, the social hub year-round. Handis has built dozens of these enclosures in the Pacific Northwest — we know the sight-line math (block the neighbor's second-story window while keeping the kitchen-window view open from the house), the wind-funnel math (the privacy screen also breaks the wind), and the rain math (the 3-inch-spaced pergola rafters block 70 percent of vertical rain). Pure carpentry. The tub electrical is already in place. Two to four working days.
Sight-line mapped at the estimate visit — blocks the specific neighbor view, keeps the house view
We walk the property at the estimate visit and identify exactly which neighbor sight-lines need to be blocked (the second-story window across the property line, the kitchen window from the next-door house, the deck on the property behind) and what post heights and slat spacing block those specific sight-lines. The privacy detail is matched to the actual problem rather than blanket-screening every side. The result is a tub that has privacy from neighbors while keeping the view from the house intact (sitting in the tub, looking back at the house — that view stays open, often through a cedar slat pattern with wide spacing for the through-view).
Cedar built for PNW weather — kiln-dried local supply, stainless throughout
Cedar enclosures hold up in PNW rain for 15 to 20 years if built correctly. We use kiln-dried Western red cedar from local PNW suppliers (Dunn Lumber, McLendon, Crosscut Hardwoods) — never big-box-store cedar that is sometimes wet-stacked and twists or checks within months in PNW climate. All cedar joints stainless-fastened (never galvanized — galvanized fasteners stain cedar over time). Posts through-bolted or anchor-bolted to the appropriate substrate; concrete-set posts on grade go below the local frost line. Slat spacing chosen for the privacy detail desired (3/4-inch for full privacy with airflow, 1/4-inch for screen-only).
Pergola rain math — 3-inch slat spacing blocks 70 percent vertical rain
A cedar pergola overhead with 3-inch-spaced rafters blocks roughly 70 percent of vertical rain — face-rain during a soak reduces to a fine mist instead of a steady drip. We confirm the slat-spacing choice with the homeowner at the estimate visit based on the rain-vs-open-sky preference (3-inch for maximum rain blocking, 4 to 6-inch for the more open-sky feel that still defines the space). The pergola structure is a cedar 6x6 post and 4x6 header and rafter assembly — stainless-fastened, through-bolted at the post bases, designed to carry the local snow load (typically 20 pounds per square foot in the Seattle area).
Honest about what is and is not in scope — pure carpentry, electrical separate
Hot tub privacy enclosure is pure carpentry. The hot tub electrical (240V GFCI to NEC 680) is already in place from the original tub install — we work around it and never modify the existing electrical. If the project is around a new hot tub that needs electrical, we coordinate the licensed Washington L&I electrician separately on a different scope and quote; the electrician pulls the permit and handles the NEC 680 bonding. The pad under the tub also stays as-is (we do not pour a new pad on this scope — that is part of a cold-plunge-style pad project if the tub is being relocated).
Insured, background-checked, written one-year project warranty
Handis carries general liability and workers' compensation; every technician has cleared a background screening. The one-year project warranty covers cedar framing, enclosure construction, pergola structure, decking surround (where included), and finishes — if anything in our carpentry scope fails inside a year, we come back and fix at no charge. Cedar that has silvered naturally or been oiled is normal wear; the warranty covers structural and workmanship issues.

We send back a clear estimate and a project timeline.
Customer Reviews
Hot tub privacy enclosure reviews from verified Seattle-area Handis customers.
Hot tub privacy enclosure in our Wallingford back yard — neighbors built a tall fence and a second-story window that looked directly into our tub. Handis built a cedar slat privacy screen on three sides (the side facing the house stayed open for the view) and a small pergola overhead so the rain does not hit the face during a soak. Three working days. The tub is usable again year-round and the cedar will silver naturally over the next year.
Full four-sided enclosure with pergola for our Madison Park back-yard hot tub. We have neighbors close on three sides and wanted total privacy — Handis built cedar slat screens on all four sides with a swing access door at the back for tub maintenance. Pergola overhead at 3-inch rafter spacing. Four working days. The tub feels like a destination room now rather than equipment on the patio.
Cedar pergola only over our Hot Spring tub in West Seattle — the privacy was fine but the rain hitting the face during winter soaks was killing the use. Handis built a freestanding cedar pergola with 3-inch-spaced rafters that drops the face-rain to a fine mist. Two working days. We have used the tub three times a week in November and December — the rain blocking made it usable year-round.
Privacy enclosure with a decking surround for our 2005 Sundance tub in Bothell. The original install had the tub low on a concrete pad and entry from grade required climbing over the rim. Handis built a cedar decking platform around the tub at the rim height with two steps up from grade, plus a three-sided privacy screen and a pergola overhead. Five working days. Tub entry is now a no-thinking-required step-up, and the space reads as a destination.
Top-end build with full enclosure, pergola, decking surround, and a built-in cedar bench for our Caldera tub in Mercer Island. The bench has been the unexpected best detail — pre-soak and post-soak both have a comfortable seat now, and the towels stay dry inside the enclosure. Four working days. Cedar has been oiled for the warm-tone retention and looks beautiful.
