- Walk-in shower
- A walk-in shower with no tub or raised edge, just a flat floor and walls. These are a go-to for Woodinville’s tighter homes because they free up space and look modern. They’re easier to step into than tubs, but need a waterproof barrier and sloped base to stop leaks. If your current shower feels squeezed, this could be the fix, just budget for a glass screen with no frame if you want that clean look. Check out our full service list for details.
- Curbless shower
- A shower with no threshold between the shower floor and the rest of the bathroom, creating a smooth transition. Great for bathroom remodeling in homes with mobility concerns or for a spa-like feel. However, they need precise waterproofing membrane and a linear drain to handle water flow without pooling. In Woodinville’s wetter months, this design keeps water where it belongs, in the shower. Pair it with heated floor for extra comfort. Worth a look: contact the office.
- Tub-to-shower conversion
- Removing a bathtub and replacing it with a shower (often a walk-in or curbless style). This is one of the most common bathroom renovations in Woodinville, especially in homes built before the 1990s when showers were an afterthought. It frees up space and modernizes the look, but watch out for plumbing relocations, hidden costs can sneak in if the rough-in isn’t compatible. Always ask for a change order if the existing pipes need adjustments. Learn more about our background and licensing.
- Wet room
- A bathroom where the shower, toilet, and sometimes vanity are all in one waterproofed space, no separate tub or shower enclosure. Popular in bathroom remodeling for luxury or small spaces, but requires heavy-duty cement backer board, waterproofing membrane, and a linear drain sloped for drainage. In Woodinville’s rainy season, this design works if you’re okay with a more industrial, high-maintenance look. Not ideal for families with kids or pets.
- Floating vanity
- A vanity that looks like it’s floating with no visible legs or base cabinet. This trick makes small bathrooms, common in Woodinville’s older homes, feel bigger. The real cabinet is mounted to wall studs or hidden supports. Watch out: If your vanity feels unstable, it’s not secured right, ask your remodeler to show you the mounting hardware before they finish.
- Shower pan
- The waterproof tray or slope built into the floor of a shower to direct water to the drain. In bathroom remodeling, a poorly installed pan can lead to leaks under tile or into subfloors, costly fixes later. Look for pans with built-in waterproofing membrane or ask your contractor to use a separate membrane like RedGard. Skipping this step is a red flag in any bathroom renovation quote.
- Waterproofing membrane
- A thin, flexible layer applied under tile or to shower walls to block water from seeping into drywall or subfloors. Critical in bathroom remodeling, especially in Woodinville’s damp climate. Cheap contractors might skip it or use the wrong type, always ask to see it installed. Membranes like Schluter Kerdi or RedGard are industry standards for bathroom remodelers who do it right.
- Linear drain
- A long, narrow drain (often hidden under tile) that spreads water evenly across the shower floor for faster drainage. Used in curbless showers and wet rooms, these prevent standing water and mold. In bathroom renovations, they’re pricier than point drains but worth it for high-traffic bathrooms. If your contractor suggests a cheaper drain, ask why, it might mean poor water flow.
- Cement backer board
- A rigid board made of cement and fiberglass used as a base for tile in showers and wet areas. Unlike drywall, it won’t warp or rot when wet, essential for bathroom remodeling longevity. Thickness matters: ½-inch is standard, but ⅝-inch is better for heavy tile like large-format tile. Ask your bathroom remodeler if they’re using the right type before tiling begins.
- Thinset
- A type of mortar used to glue tile to cement backer board or other surfaces. Comes in modified (for wet areas) and unmodified (for dry areas). In bathroom renovations, modified thinset is a must for showers to prevent tile from popping off. Some contractors cut corners by using the wrong type, always verify it’s labeled for wet areas.
- Grout (sanded vs. unsanded)
- The paste used to fill gaps between tiles. Sanded grout (for joints wider than 1/8 inch) has fine sand for strength, while unsanded grout (for narrow joints) is smoother but weaker. In bathroom remodeling, unsanded grout is common for small porcelain tile, but sanded grout holds up better in high-moisture areas. Ask your contractor which they’re using, and whether they’ll seal it to prevent stains.
- Porcelain tile
- A tough, waterproof tile made by baking clay at high heat. It’s a top pick for bathrooms because it lasts, cleans easily, and comes in tons of styles. In Woodinville, it’s often used in showers and floors. Go for large tiles (12x24 inches or bigger) to cut down on grout lines, but only if your subfloor is perfectly flat.
- Large-format tile
- Tile larger than 12x12 inches, often 12x24 or 16x32 inches. Used in bathroom remodeling to create a continuous, high-end look with fewer grout lines. The trade-off? It’s harder to install correctly, requires a perfectly flat surface and skilled tilers. If your contractor suggests it for a small Woodinville bathroom, ask if they’ve done it before. Poor installation can lead to cracks or uneven floors.
- Shower niche
- A recessed shelf in a shower wall, usually above the drain, for storing shampoo or soap. Common in bathroom renovations to save counter space. Niches can be pre-formed in fiberglass or custom-built with tile. In Woodinville’s tighter bathrooms, they’re a smart way to keep essentials handy without cluttering the vanity. Just ensure it’s properly waterproofed to avoid mold.
- Frameless glass
- A shower enclosure with no metal frame, just glass panels held in place by silicone or clips. Gives a sleek, modern look in bathroom remodels but requires precise measurements to avoid leaks. In Woodinville’s humid summers, the silicone seal can degrade faster if not high-quality. Ask your bathroom remodeler about maintenance, some glass enclosures need resealing every few years.
- Exhaust fan CFM
- CFM stands for ‘cubic feet per minute,’ measuring how much air a bathroom fan pushes out. For remodels, aim for 1 CFM per square foot, so a 50 sq. ft. bathroom needs a 50 CFM fan. Woodinville’s damp air means good ventilation stops mold. Skimping on fan power (under 50 CFM) is a budget mistake, don’t leave it out.
- Comfort-height toilet
- A toilet seat height (usually 17–19 inches) designed to reduce strain on knees and back. Standard toilets sit at 15 inches. In bathroom remodeling, these are worth the slight extra cost if mobility is a concern, especially for Woodinville’s aging population. They’re also easier for kids to use. Just note: some models have higher water usage, so check the specs.
- Toilet rough-in
- The distance from the wall to the toilet’s drain connection (measured in inches). Standard rough-ins are 12 inches, but older homes often have 10-inch or 14-inch setups. If you’re doing a bathroom remodel and the new toilet doesn’t match the rough-in, you’ll need to relocate pipes, adding cost. Always confirm this measurement before buying fixtures.
- Heated floor
- Electric or hydronic heating installed under bathroom flooring to keep it warm. A luxury upgrade in bathroom renovations, especially in Woodinville’s chilly winters. Electric systems are easier to install but cost more to run; hydronic (water-based) systems are cheaper long-term but require more work. If you’re tiling, ensure the cement backer board can handle the heat output.
- Grab bar / aging in place
- A metal bar installed near toilets or showers to provide support for stability. Part of aging in place design, which modifies bathrooms for safety as needs change. In bathroom remodeling, grab bars should be mounted into studs, not drywall, and use non-slip coatings. Woodinville’s growing senior population makes these a smart, low-cost upgrade, often required for resale value.
- Change order
- A written document modifying the original bathroom remodel contract, often due to unexpected issues like rotten subfloors or plumbing relocations. Reputable bathroom remodelers won’t spring extra charges without a change order. Always review it before signing, some contractors use them to hide upcharges. In Woodinville, we provide itemized change orders with clear justifications.
- Punch list
- A final checklist of incomplete or flawed work items at the end of a bathroom renovation. Before paying, walk through with your contractor to inspect every detail, missing caulk, loose tiles, or a wobbly vanity should all be on it. Skipping this step is how homeowners end up paying for fixes later. At Nunez Bathroom Remodeling, we do a thorough punch list inspection before you sign off.
Frequently Asked Questions
I’m remodeling my Woodinville bathroom and the contractor mentioned ‘thinset’, what’s the big deal if they use the wrong type?
Thinset is the glue holding your tile to the wall or floor. Using unmodified thinset in a shower will cause tiles to pop off over time, especially in Woodinville’s damp climate. Modified thinset is waterproof and costs only a few dollars more per tube. If your contractor skips this, walk away. It’s a red flag for cutting corners in your bathroom remodel.
My Woodinville bathroom feels cramped, and the contractor suggested a ‘wet room’, is that really worth the extra cost?
A wet room combines shower, toilet, and sometimes vanity into one waterproofed space. It’s a luxury look, but the cement backer board, waterproofing membrane, and linear drain add up fast, often $1,500–$3,000 more than a traditional layout. In Woodinville’s smaller homes, it might not save space unless you’re removing a tub. Ask if you’ll need custom tile work, another hidden cost.
The contractor wants to use ‘unsanded grout’ in my shower, is that okay, or should I push for sanded?
Unsanded grout is fine for small porcelain tile gaps (under 1/8 inch), but sanded grout is stronger for wider joints. In a bathroom renovation, unsanded grout can crack or stain easier, especially in Woodinville’s hard water. If your contractor insists on it for a larger tile, ask why. Sanded grout costs about the same but lasts longer. Seal it either way to prevent mold.
