Bathroom Remodeling & Kitchen Remodeling Glossary

This glossary breaks down bathroom remodeling terms Algona homeowners hear but often misunderstand, like ‘walk-in shower’ or ‘thinset’, so you can spot red flags, ask the right questions, and avoid costly mistakes. Whether you’re tackling a full bathroom remodel or a simple tub-to-shower conversion, knowing these basics helps you work with contractors (or DIY safely) without getting played. Start here before your Algona bathroom renovation begins.

Algona’s older homes often hide outdated bathrooms with crumbling tile, leak-prone showers, or toilets that won’t stop running, and that’s before you factor in our damp Pacific Northwest climate. A bathroom remodel isn’t just about aesthetics; it’s about fixing what’s broken first. That’s why we built this glossary: to cut through the jargon so you recognize shoddy work (or a bad quote) before you sign anything. Need a full bathroom renovation or just a tub-to-shower conversion? Start here for our Algona services to see what’s possible. Or if you’re comparing contractors, check our pricing guide to spot fair vs. inflated costs.

Walk-in shower

A shower without a tub or raised threshold, just a flat floor and walls, often with a glass door. These are popular in Algona’s smaller homes because they save space and feel modern, but they require proper waterproofing (like a shower pan and membrane) to prevent leaks. If your current shower floods the bathroom, a walk-in might be the fix, but skip the DIY install unless you’re confident with tiling and drainage.

Curbless shower

A shower with no lip or curb between the floor and the shower area, creating a smooth look. Great for aging-in-place projects in Algona, but tricky to install right, water must drain perfectly to avoid puddles. Many homeowners assume it’s just ‘lowering the shower,’ but the real work is in the slope of the floor and the drain system. Ask us about grab bars and slip-resistant tile if you’re planning this for safety.

Tub-to-shower conversion

Removing a bathtub and replacing it with a standalone shower (or walk-in). Common in Algona’s 1970s-era homes where tubs are outdated or leaky, but it’s more than just ‘taking out the tub.’ You’ll need to adjust plumbing, reinforce floors, and often upgrade the shower pan. See our cost guide, this can range from $1,500 to $5,000 depending on tile and fixtures.

Wet room

A bathroom where the shower, toilet, and sink are all in one space with no walls separating them, just waterproof floors and walls. Popular in Europe but rare in Algona due to our humidity and mold risks. If you love the open look, you’ll need heavy-duty ventilation (a high-CFM exhaust fan) and non-porous materials like porcelain tile. Not all Algona homes can handle this, ask us first.

Floating vanity

A vanity that appears to ‘float’ on the wall with no visible base cabinet. The cabinet is actually mounted inside the wall, creating a sleek look. In Algona’s smaller bathrooms, this frees up floor space, but it requires precise plumbing and electrical work. Cheap floating vanities often sag over time; ours are built to last with reinforced framing. See our kitchen remodeling work for similar space-saving tricks.

Shower pan

A waterproof tray or slope built into the floor of a shower to direct water to the drain. In Algona’s older homes, many shower pans are cracked or missing entirely, leading to water damage under the tile. A proper pan (often made of fiberglass or cement) is critical, skipping it is a recipe for mold and structural issues. We inspect pans during free estimates, don’t assume yours is fine.

Waterproofing membrane

A thin, flexible sheet (like RedGard or Schluter Kerdi) applied under tile to block water from seeping through cracks. Essential for showers, wet rooms, and even around toilets in Algona’s damp climate. Many contractors cut corners here, if yours doesn’t mention this step, walk away. See our leak-proofing process for how we do it right.

Linear drain

A long, narrow drain (often hidden under tile) that spreads water across the shower floor for a smooth look. Popular in modern designs but harder to install correctly, water must flow evenly to avoid puddles. In Algona’s smaller bathrooms, a linear drain can make a tiny shower feel bigger, but it’s not a fix for poor drainage. Ask about our drain solutions before choosing tile.

Cement backer board

A hard, moisture-resistant board (like HardieBacker) installed under tile to provide a solid, flat surface. Required for showers and wet areas in Algona’s humid climate, gypsum drywall will rot if exposed to water. Some contractors use thinner boards to save money, but that leads to cracks and leaks. We only use ½-inch backer board for durability.

Thinset

A thick, sand-based adhesive used to glue tile to backer board or walls. Comes in ‘modified’ (latex) and ‘unmodified’ (cement-based) types, modified is easier to work with but less waterproof. In Algona’s showers, we always use unmodified thinset for a watertight bond. Poor thinset is a leading cause of tile failures, don’t skip this step.

Grout (sanded vs. unsanded)

The cement-like material between tiles that seals gaps. Sanded grout (for joints wider than 1/8 inch) is stronger but can stain; unsanded (for narrow joints) is smoother but less durable. In Algona’s bathrooms, we recommend epoxy grout for showers, it’s waterproof and won’t mold. See our tile installation details for why grout color matters too.

Porcelain tile

A dense, water-resistant ceramic tile made by firing clay at high temperatures. Unlike ceramic, it won’t absorb water or stain easily, making it ideal for Algona’s showers and floors. Porcelain comes in large-format sizes (see below) and can mimic stone or wood. Ask about our scratch-resistant glazes, cheap porcelain chips faster.

Large-format tile

Tile larger than 12x12 inches (often 24x24 or bigger) that creates a smooth, modern look with fewer grout lines. Popular in Algona’s bathroom remodels for its sleek appearance, but it requires a perfectly flat surface to avoid visible seams. Large-format porcelain tile is also easier to clean, great for busy families. See our tile options for pros and cons.

Shower niche

A recessed shelf in the shower wall for shampoo, soap, or a phone. Often built into the tile during installation, but some contractors add them later as an upsell. In Algona’s smaller showers, niches can make storage tricky, opt for a deep niche (6+ inches) if you want to store bottles without cluttering the floor. We design niches to match your tile for a custom fit.

Frameless glass

A shower enclosure with no metal frame, just glass panels held by silicone or stainless steel clips. Looks ultra-modern but requires precise measurements to avoid leaks. In Algona’s windy areas, frameless glass can rattle if not installed properly. See our glass shower options, we use tempered glass for safety.

Exhaust fan CFM

CFM stands for ‘cubic feet per minute,’ measuring how much air a bathroom fan moves. Algona’s humidity demands at least 50 CFM for a small bathroom, 70+ for larger ones. A weak fan leads to mold, many older homes have 25 CFM fans that do nothing. We install Energy Star fans with moisture sensors to prevent mold growth.

Comfort-height toilet

A toilet seat height (17–19 inches) designed to reduce strain on knees and back, ideal for aging-in-place projects in Algona. Standard toilets sit at 15 inches, which can be hard on older adults or those with mobility issues. See our grab bar and toilet solutions for safe, ADA-compliant options.

Toilet rough-in

The distance (usually 12 inches) from the wall to the toilet’s drain connection. If your toilet wobbles or leaks at the base, the rough-in might be off. In Algona’s older homes, rough-ins are often 10 or 14 inches, we adjust plumbing to standardize it for easier repairs. Never DIY this, it’s a plumbing code violation.

Heated floor

Electric or hydronic heating cables installed under bathroom flooring to keep it warm. A luxury in Algona’s chilly mornings, but it adds $1,000–$3,000 to a remodel. Electric systems are easier to install; hydronic (hot water) is cheaper to run long-term. Ask about radiant floor heating, we’ll help you pick the right type.

Grab bar / aging in place

A sturdy metal bar installed near toilets or showers to help seniors or those with mobility issues steady themselves. Required by code in some Algona remodels for safety. Cheap grab bars pop off, ours are welded to studs and rated for 250+ pounds. See our aging-in-place solutions for discreet, stylish options.

Change order

A written request to modify your bathroom remodel’s scope or materials after the contract is signed. Contractors often add change orders for ‘upgrades’ (like premium tile) that cost more. Always get change orders in writing, verbal promises aren’t binding. We charge a 10% fee for last-minute changes to avoid surprises.

Punch list

A final checklist of minor fixes (like caulk touch-ups or loose tiles) before a remodel is considered complete. Many contractors rush this step to meet deadlines, leaving you with hidden issues. We do a thorough punch list, no job is done until it’s perfect. See our process for how we handle final inspections.
