Start with the basics: What’s the difference between a tub-to-shower conversion and a full wet room? Or jump straight to the terms you’ve heard but didn’t dare ask about.

Walk-in shower

A shower without a tub or raised lip, just a flat floor and walls. These are popular in bathroom remodels because they’re easier to step into (great for aging in place) and often use less water than tubs. In Tukwila’s tighter homes, they also free up space for a floating vanity or extra storage. The trade-off? Proper waterproofing membrane and shower pan installation are a must to prevent leaks under the tile. Need help picking a shower style that fits your budget?

Curbless shower

A shower that blends smoothly with the bathroom floor, eliminating the lip at the entrance. This design is ideal for bathroom renovations where accessibility matters, like for families with young kids or aging parents. However, it requires careful waterproofing membrane work and a linear drain to handle water flow without pooling. In Tukwila’s rainy climate, this setup can also mean more frequent maintenance if not installed correctly.

Tub-to-shower conversion

Removing an existing tub and replacing it with a shower (often a walk-in shower or curbless shower). This is one of the most common bathroom remodeling projects in Tukwila because it’s less expensive than a full tear-out and can modernize a space quickly. The challenge? Older homes may need updated plumbing or toilet rough-in adjustments to handle the new setup. See how much this costs in Tukwila vs. nearby areas like Burien.

Wet room

A bathroom where the shower, toilet, and sometimes vanity are all in one open space with no walls, just a single waterproofing membrane covering the entire floor and lower walls. Wet rooms are trendy in bathroom remodels for their sleek look, but they demand high-end materials and ventilation (like a CFM-rated exhaust fan) to prevent mold. In Tukwila’s humid summers, this means extra attention to cement backer board and tile sealing.

Floating vanity

A vanity that appears to float on the wall with no visible cabinet base, creating an illusion of more space. These are a staple in bathroom renovations because they make small Tukwila bathrooms feel larger and often include built-in storage. The catch? They require sturdy wall supports and precise plumbing for the sink and toilet rough-in. Learn how to choose a vanity that won’t break your budget.

Shower pan

A waterproof tray or slope built into the floor to direct water toward the drain during a shower. It’s hidden under tile but critical, poor installation leads to leaks that damage subfloors and drywall. In bathroom remodeling, a well-built pan can save you thousands in future repairs. Cheap pans (or skipping one entirely) are a red flag in quotes from bathroom remodelers.

Waterproofing membrane

A thin, bendable barrier applied to shower walls and floors to stop water from damaging drywall or subfloors. In Tukwila’s damp weather, this is a must for walk-in showers or wet rooms. Top brands like RedGard or Schluter Kerdi set the standard, but some contractors skimp on quality. Always check the installation, here’s how to tell if it’s done right.

Linear drain

A long, narrow drain (often hidden under tile) that spreads water evenly across the shower floor, preventing puddles. These are key for curbless showers and wet rooms but require precise shower pan sloping. In bathroom remodels, they’re pricier upfront but reduce long-term maintenance. See how drain choices affect your Tukwila remodel costs.

Cement backer board

A rigid board made of cement fibers, used as a base for tile in showers and backsplashes. It’s water-resistant and prevents tile from cracking over time. In bathroom renovations, Durock or HardieBacker are top picks, but some contractors use cheaper alternatives that fail in Tukwila’s humidity. Always verify it’s properly sealed with thinset before tiling.

Thinset

A thick, glue-like mortar used to stick tile to cement backer board or other surfaces. It’s stronger than regular mortar and flexible enough to handle minor shifts in the wall. In bathroom remodeling, using the wrong type (or skipping it for mastic) can cause tiles to pop off. Ask your bathroom remodeler to show you the thinset they’ll use, this is where cost-cutting leads to headaches.

Grout (sanded vs. unsanded)

The paste between tiles that seals gaps and holds them in place. Unsanded grout (finer particles) is for small tile gaps (under 1/8 inch), while sanded grout (coarser) fills wider gaps. In bathroom remodels, unsanded grout is easier to clean but less durable for high-moisture areas like showers. Sanded grout resists cracking but stains more. Learn which grout saves you time (and money) long-term.

Porcelain tile

A dense, water-resistant ceramic tile made by firing clay at high heat. It’s the gold standard for bathroom remodeling showers and floors because it’s durable, easy to clean, and won’t absorb water like natural stone. In Tukwila, porcelain is also a smart choice for large-format tile (bigger planks) because it hides imperfections better than ceramic. See how tile size affects your project timeline.

Large-format tile

Tile planks or slabs larger than 12x24 inches, often 24x48 inches or bigger. These reduce grout lines (fewer places for mold) and speed up installation in bathroom remodels. In Tukwila’s smaller homes, they create a smooth, modern look, but require precise shower pan and waterproofing membrane work to avoid gaps. Large-format tile can cut labor costs, here’s how.

Shower niche

A recessed shelf in the shower wall, usually for shampoo or soap. Niches add convenience to walk-in showers but must be properly sealed to prevent water damage. In bathroom renovations, they’re often built into cement backer board and tiled to match the rest of the shower. Want a niche that won’t trap grime? Ask about these details.

Frameless glass

Shower enclosures with no metal frame, just glass panels held by clips or silicone. They look sleek and modern but require precise measurements to avoid leaks. In bathroom remodeling, frameless glass is pricier upfront but can add resale value in Tukwila’s competitive housing market. See how glass choices impact your budget.

Exhaust fan CFM

CFM (cubic feet per minute) tells you how much air a bathroom exhaust fan pushes out. The National Kitchen and Bath Association recommends at least 50 CFM for compact powder rooms and 110 CFM for bigger bathrooms or showers in Southcenter homes. Tukwila’s damp weather makes poor ventilation a mold risk, skipping a strong fan can shorten your remodel’s durability. Check how better airflow protects your investment.

Comfort-height toilet

A toilet seat that’s 1–2 inches higher than standard models (about 17 inches from floor to seat). These reduce strain on knees and hips, making them ideal for aging in place or families with kids. In bathroom remodels, they’re a small upgrade with big comfort payoffs, just ensure your toilet rough-in can accommodate them. See how toilet height affects your project’s plumbing costs.

Toilet rough-in

The distance from the wall to the toilet’s drain connection (usually 12 inches, but can vary). If your bathroom remodel replaces plumbing, this must match the new toilet’s rough-in. Mismatches mean costly adjustments, so measure before buying fixtures. Need help checking your home’s rough-in? We’ll verify it during your free estimate.

Heated floor

Electric or hydronic heating cables installed under tile to warm floors in bathrooms. In Tukwila’s chilly winters, this is a luxury upgrade that also prevents mold by keeping surfaces dry. Installation adds to bathroom remodeling costs but pays off in comfort and resale value. See how radiant heat affects your budget.

Grab bar / aging in place

A sturdy bar installed near toilets or showers to provide support for balance, especially for seniors or those with mobility challenges. In bathroom renovations, grab bars must be ADA-compliant (supporting 250+ pounds) and installed into studs, not drywall. Tukwila homeowners planning to stay put long-term often add them during remodels to avoid future modifications. Learn how aging-in-place features boost home value.

Change order

A written request to modify the original scope of your bathroom remodel, like swapping tile or adding a walk-in shower. Reputable bathroom remodelers won’t let you sign one without a new quote, so always get changes in writing. In Tukwila, unexpected change orders are a top complaint against fly-by-night contractors. Here’s how to avoid surprise charges.

Punch list

A final checklist of minor fixes (like caulk gaps or touch-up paint) needed before a bathroom renovation is considered complete. Skilled bathroom remodelers walk you through it before final payment, so you’re not left paying for oversights. In Tukwila, we include a punch list in every project to ensure nothing slips through the cracks. See how we handle final inspections differently.
