And if you’re unsure whether your bathroom needs work, check these 7 red flags first.

Walk-in shower

A shower with no lip or threshold between the floor and the shower area, making it easier to step in, especially for aging in place or homes with kids. Unlike tub-to-shower combos, these are fully open, but they require careful waterproofing and a linear drain to prevent leaks. In Arlington’s wetter months, proper drainage is non-negotiable, skip the DIY and hire a pro to get it right. Learn more about our full list of services page.

Curbless shower

Same as a walk-in shower but often refers to designs where the shower floor is flush with the bathroom floor, creating a smooth look. This style is popular in modern bathrooms but demands a well-sloped shower pan and a high-quality waterproofing membrane to handle water runoff. Arlington’s older homes may need structural adjustments to pull this off safely. Background in request a free estimate / contact us.

Tub-to-shower conversion

Removing a bathtub and replacing it with a standalone shower (or walk-in shower). This frees up space and can modernize a bathroom, but it often requires relocating plumbing or upgrading the shower pan. If your tub’s drain isn’t up to code, this is a chance to fix it, don’t let a cheap conversion turn into a leaky mess. Take a look at the team behind the work.

Wet room

A bathroom where the shower, toilet, and sometimes vanity are all in one open space with no walls, just a waterproof floor and ceiling. These are trendy but high-maintenance, requiring heavy-duty waterproofing and ventilation. Arlington’s humidity isn’t ideal for wet rooms unless you’re prepared for extra upkeep. For the specifics, see where we work page.

Floating vanity

A wall-mounted vanity with no visible base, making a bathroom look bigger. These need strong wall anchors and hidden plumbing. In Arlington’s tight spaces, floating vanities open up small bathrooms, but bad installs mean sagging and leaks.

Shower pan

The sloped base under a shower (usually cement or fiberglass) that drains water. A bad pan leads to leaks, mold, and floor damage. Skip flimsy pre-made pans, custom cement bases last 20+ years and avoid costly fixes.

Waterproofing membrane

A thin, flexible layer (like redgard or similar) applied under tile to block water from seeping into walls or subfloors. Without it, moisture wicks into drywall, causing rot and mold, especially problematic in Arlington’s damp winters. This isn’t optional; it’s the difference between a shower that lasts and one that fails.

Linear drain

A long, narrow drain (often hidden under tile) that spreads water evenly across the shower floor, reducing pressure on one spot. These are key for curbless showers but require precise installation to avoid clogs. Arlington’s hard water makes linear drains a smart choice, just don’t skimp on the mesh filter.

Cement backer board

A rigid board (like HardieBacker) installed under tile to provide a stable, moisture-resistant base. Unlike drywall, it won’t swell or crumble when wet. This is a must for showers and wet areas, no exceptions.

Thinset

A thick, sanded or unsanded adhesive used to glue tile to backer board or walls. Sanded thinset is for floors; unsanded is for walls. Poor thinset application causes tiles to pop off over time. Arlington’s tile pros know the difference, don’t let a contractor cut corners here.

Grout (sanded vs. unsanded)

Sanded grout (with fine particles) fills wider gaps (1/8”+) and resists cracking, while unsanded grout is for tight spaces (1/16” or less). Sanded grout is easier to work with but can stain more. Unsanded grout is a pain to apply, hire a pro if you’re not confident.

Porcelain tile

A dense, durable ceramic tile that’s waterproof and scratch-resistant, ideal for showers and floors. It’s more expensive than ceramic but lasts longer. In Arlington’s bathrooms, porcelain is the gold standard, ceramic just won’t hold up.

Large-format tile

Tiles 24”x24” or larger that create a smooth, modern look with fewer grout lines. They’re faster to install but require precise cutting and a level subfloor. Large-format tile looks stunning but hides imperfections, get the prep right or regret it later.

Shower niche

A recessed ledge in the shower wall where you store soap or shampoo. If it’s not sealed right, mold will grow there. Cheap pre-cut niches fall apart quick, custom waterproof ones hold up and stay dry.

Frameless glass

Shower enclosures with no metal frame, held up by the glass itself. These look sleek but require precise measurements and heavy-duty glass. Frameless glass is a luxury item, if your contractor isn’t experienced, stick with framed.

Exhaust fan CFM

CFM (cubic feet per minute) shows how much air a bathroom fan moves. Arlington’s humidity needs 50–110 CFM, less means mold. 50 CFM is the minimum; 80+ cuts moisture in bigger bathrooms.

Comfort-height toilet

A toilet seat height (17”–19”) designed to reduce strain on knees and back, ideal for aging in place or taller users. Standard toilets sit at 15”. If you’re over 5’6” or have mobility concerns, comfort-height is worth the upgrade.

Toilet rough-in

The distance (usually 12” or 10”) from the wall to the toilet’s drain connection. Changing this requires moving pipes, which is costly. Measure yours before planning a remodel, mismatched rough-ins add thousands to the bill.

Heated floor

Electric or hydronic heating installed under bathroom floors for warmth. Electric systems are easier to install; hydronic requires plumbing. In Arlington’s chilly winters, heated floors are a big improvement, but they’re not cheap.

Grab bar / aging in place

Wall-mounted bars for support, often required in ADA-compliant bathrooms. They’re not just for seniors, helpful for anyone with balance issues or after knee surgery. Installing grab bars during a remodel costs less than retrofitting later.

Change order

A written request to modify the original remodel plan (e.g., upgrading tile or moving plumbing). Always get a signed change order to avoid surprises on the final bill. Verbal agreements don’t count, insist on paper.

Punch list

A final checklist of incomplete or flawed work items (e.g., loose tiles, missing caulk) before project closeout. A good contractor walks you through it before handing over the keys. Skip the punch list? You’ll pay for it later with repairs.
