Tumwater’s older homes and rainy climate mean your bathroom remodel needs to balance style with smart waterproofing and durability. Terms like ‘curbless shower’ or ‘thinset’ sound simple until you’re staring at a leak or a cracked tile. This glossary breaks down what each phrase really means, so you can ask the right questions before your contractor walks out the door. Need a full list of what we handle?

Walk-in shower

A shower without a raised lip or threshold, designed for easy step-in access, ideal for aging-in-place projects or homes with uneven flooring. In Tumwater’s older homes, these often replace tubs to save space and improve safety. Poor installation (like skipping a proper shower pan) leads to water pooling under the tile, which we see too often in our areas/tumwater remodels. Always specify a sloped floor and a waterproofing membrane.

Curbless shower

Same as a walk-in shower, but with a smooth transition to the bathroom floor, no curb at all. This creates a ‘wet room’ feel but requires extra waterproofing and a linear drain to handle water flow. Tumwater’s high humidity makes this a smart choice if you want to avoid mold. Skip the membrane, and you’ll regret it when grout starts staining. We’ve fixed enough leaks from cut-rate installs to know: this isn’t a DIY job.

Tub-to-shower conversion

Removing a bathtub and replacing it with a shower (or walk-in). In Tumwater’s 1970s-era homes, this often reveals outdated plumbing that needs upgrading. The real cost isn’t the tile, it’s moving pipes or fixing a cracked shower pan. Ask your contractor if they’ll handle all the demolition, not just the pretty parts. Our blog/5-hard-truths-bathroom-remodeling-near-tumwater covers the hidden fees you’ll miss if you don’t plan ahead.

Wet room

Wet Room Floors: The Tumwater Mistake That Ruins Bathrooms

Floating vanity

A vanity with no visible legs or base cabinet, it appears to ‘float’ on the wall. In Tumwater’s smaller bathrooms, this saves space but requires structural support (hidden brackets or studs). Cheap vanities wobble over time. We recommend solid wood or metal frames, not particleboard. Need a vanity that won’t sag? Our areas/tenino and areas/yelm clients love our sturdier options.

Shower pan

The waterproofed base under your shower tile, usually made of fiberglass or cement. In Tumwater’s older homes, we often find rotted subfloors hiding under the old tub, so the pan isn’t just about drainage, it’s about stopping leaks. A fiberglass pan is cheaper but can crack; cement lasts longer but takes days to cure. We use high-density cement for our areas/lacey and areas/olympia projects, no shortcuts.

Waterproofing membrane

A thin, rubbery sheet (like RedGard or Schluter Kerdi) applied under tile to block water seepage. Tumwater’s damp winters make this non-negotiable for showers, tubs, and even some vanity areas. Skimp here, and you’ll get mold behind the tile, or worse, a flooded subfloor. We apply it before tile, not as an afterthought. See our tips for spotting shoddy waterproofing in existing bathrooms.

Linear drain

A long, narrow drain (often hidden under tile) that spreads water evenly across the floor, used in curbless showers and wet rooms. In Tumwater’s tight spaces, these let you design a sleek look without sacrificing drainage. But they’re expensive to install right, cheap ones clog fast. We use stainless-steel grates and high-flow models to handle our rainy season. Not all drains are equal.

Cement backer board

A rigid board (like Durock) installed under tile to provide a solid, moisture-resistant base. In Tumwater’s humid climate, you cannot use drywall under tile, it’ll swell and crack. Backer board needs thinset mortar to stick, and the seams must be taped and sealed. We use 1/2-inch boards for showers, 1/4-inch for walls. Cut corners, and your tile will pop off in a year.

Thinset

A thick, glue-like mortar used to stick tile to backer board or walls. There are two types: modified (for wet areas) and unmodified (for dry walls). In Tumwater’s showers, we always use modified thinset, it’s waterproof and won’t wash away. Unmodified thinset under a shower tile? That’s a recipe for a loose tile and a flooded bathroom. We mix ours on-site for freshness.

Grout (sanded vs. unsanded)

The cement-like material between tiles. Sanded grout (1/8-inch or larger gaps) is for wider tiles; unsanded is for small tiles or glass. In Tumwater’s bathrooms, we use epoxy grout in showers, it’s waterproof and won’t stain like cement grout. Sanded grout in a shower? It’ll crumble. Unsanded in a large-format tile job? It’ll crack. Pick the wrong one, and you’ll be regrouting in six months.

Porcelain tile

A dense, water-resistant ceramic tile that’s the gold standard for showers and floors. It’s durable, easy to clean, and won’t absorb water like ceramic. In Tumwater’s homes, we recommend porcelain for any wet area, it’s worth the upfront cost. Cheap ceramic tile? It’ll chip and stain. We stock large-format porcelain to minimize grout lines (fewer lines = less grout to fail).

Large-format tile

Tiles 12x24 inches or larger, which create a smooth look with fewer grout lines. In Tumwater’s smaller bathrooms, these make spaces feel bigger. But they require perfect subfloor prep, any bump or uneven spot shows. We use laser-guided tile cutters and self-leveling compound to avoid the ‘floating’ edges you see in DIY jobs. Big tiles look great but need pro installation.

Frameless glass

A shower enclosure with no metal frame, just glass panels held by clips. It looks modern but requires precise measurements and tempered glass. In Tumwater’s homes, we’ve seen cheap frameless showers bow over time (thanks to humidity) or leak at the seals. We use 1/2-inch thick glass and stainless-steel hardware. Framed glass is cheaper, but frameless? It’s a statement piece, install it wrong, and it’s a statement about your contractor’s skills.

Comfort-height toilet

A toilet seat height (17–19 inches) designed to reduce strain on knees and back. In Tumwater’s older homes, we often replace low toilets with comfort-height models for aging homeowners. The height matters more than you think, especially if you have mobility issues. We recommend the Kohler Wellworth or American Standard Comfort Height lines. Cheap toilets wobble; these don’t.

Grab bar / aging in place

A sturdy bar installed near toilets or showers to help with balance, critical for aging-in-place designs. Tumwater’s older homes often need these retrofitted for safety. We use suction-cup bars for rentals (temporary) and welded bars for permanent installs. Code requires them to support 250–500 pounds. Skip the grab bar, and you’re risking a fall. We install them at the right height (33–36 inches) for most adults.

Punch list

The final checklist of unfinished or damaged items at the end of a remodel. In Tumwater, we’ve seen contractors skip punch lists, leaving homeowners to chase down missing caulk, loose tiles, or a toilet that doesn’t flush. We do a detailed walkthrough before you pay, with photos. No item left unchecked. Our blog/tumwater-bathroom-remodeling-guide-2024 explains how to spot a contractor who’ll leave you holding the punch list.
