Bathrooms are high on a lot of wish lists right now. In the 2025 Remodeling Impact Report, Realtors named a bathroom renovation among the projects with the biggest increase in demand (35%), behind a kitchen upgrade and new roofing (NARI summary of the report). If you're investing in one, here's how to get it right the first time.
Mistake 1: Relying on One Overhead Light
A single ceiling fixture puts shadows exactly where you need light: under your eyes and chin at the mirror. The fix is lighting at face height. Sconces on each side of the mirror (or one above a smaller mirror) give even, flattering light for shaving, makeup and everything in between. Plan the electrical for them before the walls are closed up.
For a warm, classic look, this brushed brass three-light vanity fixture with globe shades works over a single vanity. Keep the overhead light too, and put it on a dimmer for nighttime.
Mistake 2: Skimping on Ventilation
This is the bathroom remodel mistake nobody sees until the paint starts peeling. The EPA notes that ventilation is especially important in bathrooms to remove unwanted moisture, which helps prevent mold and mildew, and recommends checking that your bathroom fan works properly during a renovation (Remodeling Your Home and Indoor Air Quality, U.S. EPA).
When you replace the fan, look for a quiet model sized for your room, since a loud fan is a fan nobody turns on. ENERGY STAR certified ventilation fans that include lighting use 70% less energy on average than standard models (Ventilation Fans, ENERGY STAR). A quiet option many contractors install is the Panasonic WhisperCeiling bath fan. If you want to see how damp the room really gets, a small Govee hygrometer tracks humidity on your phone.
Mistake 3: Forgetting Where Everything Will Go
A beautiful floating vanity with no drawers looks wonderful on the first day and cluttered by the second week. Before you choose a vanity, make a quick list of what lives in the bathroom: towels, hair tools, toiletries, cleaning supplies, extra paper. Then give everything a place.
- Choose drawers over doors in the vanity when you can. Drawers keep things visible and easy to reach.
- Add a recessed medicine cabinet or a niche between the studs for everyday items.
- Use open shelving under the vanity or on the wall for rolled towels and baskets.
Mistake 4: Choosing Tile Before the Layout
It's tempting to start with the fun part, but tile should come after the layout. Decide where the shower, toilet and vanity go, how big the shower is, and where the niche sits, then pick tile that fits those dimensions. A shower niche should line up with your tile grout lines and sit where you can reach it without stepping into the water.
Keep the palette edited, too. One statement tile (on the floor or the shower wall) plus one or two quieter supporting tiles always looks more pulled together than four competing patterns. The Tile Shop has a good gallery of shower layouts and niche placements to study before you commit (Shower Tile Design Ideas, The Tile Shop).
Mistake 5: Ignoring the Fixtures You Touch Every Day
Faucets, shower valves and towel hooks get used more than anything else in the room, so they're worth a little extra thought. Hold a faucet before you buy it if you can, check that the spout reaches comfortably over the sink, and make sure the finish matches or intentionally contrasts with your hardware and lighting.
It's also a good moment to save water. According to the EPA, WaterSense labeled bathroom sink faucets that use a maximum of 1.5 gallons per minute can reduce a sink's water flow by 30 percent or more from the standard 2.2 gallons per minute without sacrificing performance (Bathroom Faucets, EPA WaterSense).
How to Avoid Bathroom Remodel Mistakes Before You Start
Draw the room to scale, mark the lighting and outlets, list your storage needs, and choose the layout before you shop for tile and fixtures. That one planning session prevents almost every regret on this list.

Bathroom Remodel FAQ
What is the most common bathroom remodel mistake?
Poor lighting and poor ventilation. Both are easy to plan for while the walls are open, and both are much harder and more expensive to fix after the tile is in.
What should I choose first in a bathroom remodel?
The layout. Decide where the vanity, toilet and shower go and how much storage you need, then choose tile, fixtures and lighting to fit.
Do I need a bathroom exhaust fan?
If your bathroom has a shower or tub, a properly working fan helps remove moisture that leads to mold and mildew. Check your local code with your contractor, and choose a quiet model so it actually gets used.
