Canyon County · City
Custom Shower Design & Construction in Nampa, Idaho
Canyon County's largest city, with a big stock of 1950s-to-1970s homes where the original shower has never been touched.
Short answer
Nampa's shower work is driven by age rather than ambition. A large share of the city's housing dates from the 1950s through the 1970s, which means original steel tubs with tiled surrounds set directly on mortar or, worse, tile over drywall. These assemblies are typically at or past the end of their life, and the scope is almost always a full rebuild of the wet area rather than a refresh. Newer subdivisions on the north and east sides bring the same corner-tub-and-small-shower pattern found in Meridian.
Housing stock in Nampa and the showers it produces
- Pre-war and 1940s homes near downtown Nampa with small original bathrooms and shower plumbing added after the fact.
- A substantial 1950s-to-1970s stock where the shower is a steel tub with a tiled or fibreglass surround, frequently on its original waterproofing.
- 1990s and 2000s subdivisions on the north and east sides with the familiar corner tub and undersized shower pairing.
- Newer construction near the Idaho Center and toward Happy Valley with adequate footprints and builder-grade wet areas.
What we build in Nampa
- Tile set over drywall in a 1960s surround is the most common failure we open up in Nampa. There is no repair for it — the assembly comes out to the studs and is rebuilt with a real membrane.
- Mid-century bathrooms here are small, so the highest-value moves are a well-placed niche, a compact bench or fold-down seat, and a clear glass panel instead of a curtain and a bulkhead.
- Where the tub is the only one in the house, we discuss keeping it before converting. Resale considerations in this housing stock are a legitimate factor and we will not pretend otherwise.
- Older Nampa framing is often irregular enough that wall correction before tile is a genuine part of the work, particularly with large-format tile.
Permits and jurisdiction
Permit thresholds, inspection sequences and contractor-registration requirements are set locally and change over time. We confirm current requirements with the authority having jurisdiction before work starts, and you should expect any shower contractor to tell you which office that is. In Nampa that is the City of Nampa building safety department.
Nampa's older housing is largely wood-framed over crawlspaces, which supports a recessed curbless entry. Post-2000 subdivision homes on the fringes are more often slab-on-grade, where a flush entry means either cutting the slab or raising the bathroom floor — we tell you which applies after looking, not before.
Nampa is supplied from municipal wells and the water is hard. On a rebuild we usually recommend replacing the shower supply lines and the mixing valve while the wall is open, since scale-related valve problems are common in this housing stock and the wall will not be open again.
Our guide on what to ask a shower contractor covers the permit, scope and waterproofing questions worth asking before you sign anything.

Preparing for the build
Before the first day, clear the bathroom and the route to it, take anything off the walls that shares framing with the shower, and tell us which bathroom stays in use and where the crew can park. We bring floor protection, door containment and dust control, isolate the water supply at a point we show you, and clean the work area at the end of each day.
- Selections — tile, grout, valve trim, drain and glass — are confirmed before demolition so a lead time cannot stall the build.
- In a single-bathroom home we sequence the work so the shower is out of service for the shortest possible stretch, and we say up front how long that is.
- Pets and children are kept clear of the work area; there are open drains, power tools and wet membrane in there for days.
Timeline and site conditions
Most single-shower projects in Nampa run roughly two to three weeks on site once materials are on hand: protection and demolition, framing corrections and blocking, plumbing and electrical rough-in, the complete waterproofing system with its cure and flood test, tile setting, grout, then glass. Glass is templated after tile is set, so the panel often arrives a week or two after the shower already looks finished. Your written scope carries the schedule for your specific shower rather than a stock number.
Conditions found after demolition change that schedule more often than anything else — rot at the base of a wall, a drain that is not where it should be, framing out of plane, or an older pan with no membrane behind it. We photograph what we find, price it, and get your agreement before we carry on.
What drives the price of a shower in nampa
Estimates are written after we have seen and measured the shower. We do not publish prices, because a shower quoted sight-unseen is a guess. These are the factors that move the number most, in roughly the order they matter:
- Size of the wet area and how high the tile runs — square footage of tile and membrane is the base of the estimate.
- Whether the drain and valve stay where they are. Moving either means opening the floor or the wall and coordinating a licensed plumber.
- Floor structure. A joisted floor lets a curbless pan be recessed; a slab often means either a ramped approach or cutting concrete.
- Tile choice. Large-format panels, mosaics, natural stone and any pattern that needs mitred or mapped joints all add setting time.
- Waterproofing system specified, and whether a linear drain, bench, niche or steam enclosure has to be integrated into it.
- Glass — a fixed panel, a door, low-iron glass or a custom radius each price differently.
- Conditions behind the old shower, which is why nothing is quoted before we have seen it.
Written scope, exclusions and change orders
Every project is built from a written scope that names the waterproofing system by manufacturer, the drain type, the tile and its layout, the glass, the schedule and the price. It also lists what is excluded, because that is where disputes come from.
Typically included
- Protection, containment, demolition and disposal
- Framing corrections and blocking for benches, niches and grab bars
- Plumbing and electrical rough-in for the valve, drain and any light or fan in the wet area
- The complete waterproofing system, flood test and pan slope verification
- Tile setting, grout, sealing where the material requires it
- Glass templating and installation, final clean and a punch-list walkthrough
Typically excluded and stated as such
- Work outside the shower: vanities, mirrors, bathroom flooring, paint beyond patching
- Hidden rot, mould remediation or structural repair discovered after demolition
- Moving walls, windows or the room's ventilation route
- Whole-house water treatment, though we will tell you when hard water is the real problem
- Owner-supplied materials, which we install but do not warrant
Anything that changes the scope becomes a written change order with its price and schedule effect, agreed before the work is done. Nothing is carried out on a verbal instruction.
Permits and inspections
A like-for-like tile shower replacement often needs no permit, while relocating a drain, altering supply plumbing, changing framing or adding electrical usually does. Jurisdiction follows your address, and the Treasure Valley has several — Boise, Meridian, Eagle and Star each issue their own permits, and county addresses go through the county. We identify permit-triggering work in the written scope and confirm the requirement with the authority for your address before work starts, rather than assuming.
Warranty and aftercare
Our craftsmanship is covered by a 1-year warranty, alongside the manufacturer warranties that come with the waterproofing system and materials specified in your scope.
Idaho contractor registration RCE-57919. Bonded and insured, with the current certificate of insurance provided in writing with every estimate. At handover you get the product documentation for the waterproofing system and tile, plus written cleaning guidance suited to the surfaces we installed and to Treasure Valley water. If something is not right, tell us and we will come back. Request an estimate or call (208) 891-1890.
