Most bathroom remodel regrets come from the same handful of mistakes. We've been building bathrooms in the Capital Region since 2019, and the same issues come up in almost every "I wish we had done this differently" conversation. Here are seven mistakes worth spending extra time to avoid before you sign a contract — and what to do instead.
1. Skipping proper shower waterproofing
This is the single most expensive mistake you can make in a bathroom remodel. Many contractors (and essentially every DIY bathroom tutorial online) use cement backer board with a coat of RedGard or a plastic sheet behind the tile. That works for a few years, then fails silently. By the time you see a crack in the grout or a musty smell, water has been seeping into the wall cavity for months.
What to do instead: insist on a Schluter-Kerdi membrane system or equivalent (Laticrete Hydro Ban, USG Durock Shower System). These are bonded, pressure-tested waterproofing systems that wrap the entire shower enclosure. Cost premium over backer board: $800-$1,500 on a standard shower. Every HomeNest shower gets this treatment as a standard of care.
2. Choosing tile you'll hate in five years
Tile is one of the longest-lasting elements in a bathroom remodel. Cheap tile stays in place for 30+ years if well installed; expensive tile lasts the life of the building. Which means if you pick a very trendy tile pattern or color, you're going to look at it long after the trend passes.
The worst offenders over the past decade: bright accent strips in the middle of shower walls, diagonal-set tile (looks busy and dates fast), overly saturated earthtone tiles (peach, mauve, sage), and heavily patterned floor tile.
What to do instead:pick classic materials — white or off-white subway tile, large-format porcelain, or natural stone — with accent interest in smaller, replaceable areas like the floor or a shower niche. If you want bold color, put it in paint and towels, not tile.
3. Under-ventilating the bathroom
A bathroom exhaust fan has one job: move steam and moisture out of the room before it condenses on walls and ceilings. Most Capital Region bathrooms have undersized, noisy, or improperly-vented fans. A fan that's too small or too loud gets turned off or never turned on, and the moisture stays in the room.
What to do instead:size the fan to the room (minimum 1 CFM per square foot, but 50 CFM minimum for any bathroom, 80-100 CFM for bathrooms with showers or larger footprints). Pick a quiet fan (1.0 sones or less). Vent the fan to the exterior, not into the attic — venting into the attic just moves the moisture problem. A humidity-sensing or timer switch means the fan actually runs long enough to do its job.
4. Not planning for real storage
Every Capital Region homeowner we survey six months after a bathroom remodel says storage is what they'd change. Tiny vanities with single drawers, no wall cabinet, no linen closet access, no medicine cabinet space. The bathroom looks great in photos but frustrates every morning.
What to do instead: for a primary bathroom, plan on 6+ drawers minimum (two drawer stacks per vanity side), a medicine cabinet or wall cabinet above the vanity, and either linen closet access in the room or nearby hallway storage dedicated to bathroom supplies. For secondary bathrooms, 2-3 drawers plus one shelf or cabinet is the minimum.
Design for how you actually get ready in the morning, not for how the bathroom looks in a Pinterest photo.
5. Bad lighting
The worst bathroom lighting is a single overhead fixture casting shadows on your face at the vanity. The next worst is ceiling can lights over the vanity — same problem, differently packaged. You can't see to apply makeup or shave, and the room feels dim regardless of wattage.
What to do instead:plan for three layers of light. Vanity lighting on both sides of the mirror at face height (sconces or vertical vanity lights), ambient ceiling light (recessed cans or a flush-mount), and optional accent lighting (shower light, toe-kick light, under-cabinet strip). Color temperature matters too — 2700K-3000K is warmer and more flattering than the 4000K "daylight" bulbs that make skin look ghostly.
6. DIY plumbing in the walls
There's a category of DIY that makes sense (painting, fixture swaps, hardware updates) and a category that doesn't (plumbing inside the walls, shower valve installs, drain modifications). The second category is where DIY becomes expensive fast. A cross-threaded supply line, an under-pitched drain, or a poorly-soldered joint doesn't fail immediately — it fails six months later, inside the wall, and requires opening the wall to fix.
What to do instead:hire licensed plumbers for anything behind the wall, behind the cabinet, or below the floor. HomeNest includes plumbing as part of every bathroom remodel — we don't let clients DIY the plumbing and call us when it fails. See the scope on our bathroom remodeling page.
7. Not budgeting for hidden conditions
Every older Capital Region bathroom hides something. Cast iron waste lines near end of life. Knob-and-tube electrical running through wet walls. Previous amateur repairs covered by tile. Subfloor rotted around the toilet flange. These aren't optional once we see them — they have to be addressed, and they cost money.
What to do instead:budget a 10-15% contingency on top of your fixed- price bathroom remodel quote, and prefer contractors who scope allowances honestly upfront. HomeNest quotes include allowance lines for hidden conditions so there are no surprises — discovered work either falls inside the allowance (no additional cost) or exceeds it and we document why before proceeding. This matters more in older Albany, Schenectady, and Troy homes than newer subdivision stock.
How HomeNest prevents these mistakes
Every HomeNest bathroom project includes:
- Schluter or equivalent waterproofing system behind shower tile, not shortcut methods.
- Design review with Jeff that includes storage planning, lighting layout, and ventilation sizing.
- In-house plumbing coordination with licensed trade partners we've worked with for years.
- Hidden-condition allowances documented in every quote, with photos and pricing on any discovered work.
- A 5-Year Workmanship Warranty in writing — so if something does fail, we fix it.
For a lighter-scope project where some of these considerations are less critical, our bathroom renovation scope handles the cosmetic updates without the behind-the-wall complexity.
