What we see in Boulder bathrooms

Boulder bathrooms come with a few predictable surprises.

Boulder sits at an elevation of about 5,430 feet, and its older homes were built with one small bathroom and plumbing that is now near the end of its life. Postwar ranches have their own quirks, and the city's energy code touches the rest. Here is what usually turns up, and how we handle it.

The one tiny original bath

A Victorian in Mapleton Hill or an older home in Newlands or Whittier often has a single small bathroom for the whole house. We either make that room work harder with a smarter layout and a walk-in shower, or we add a second bath so the mornings stop being a fight.

Waterproofing done right

Most bathroom callbacks in this area are leaks from a shower that was never waterproofed correctly. We build showers with a real waterproof system behind the tile, not just backer board and hope, so the wall behind your new tile stays dry.

A bath in a pop-top or basement

Table Mesa ranches take pop-tops and second stories well, and that new primary bath is the fun part. In the older core, we add baths in a former closet or a finished lower level. Either way we plan the plumbing stack and venting so it passes inspection.

Electric and the 2024 energy code

Boulder's energy code favors electric equipment, so a heat-pump water heater is often the smart pick for a bath project, and any exterior wall we open gets insulated to the required R-value. On a large remodel the code can call for electric heating. We plan for it and have you confirm the details with the city.

Plaster walls and moved framing

In the older neighborhoods the walls are plaster over wood lath and nothing is perfectly plumb after a century. Demo is dustier and the walls are rarely straight. We seal the room off, run dust control, and shim things back so your new tile sits flat.

Historic districts and the outside wall

Interior bath work usually is not landmark-reviewed. But if we add an exterior window for light or a new vent penetration on a home in Mapleton Hill or another historic district, the city may want a Landmark Alteration Certificate first. We flag that early.

Boulder bathroom questions

What homeowners ask us.

Do I need a permit to remodel a bathroom in Boulder?
If we move plumbing, change electrical, or move a wall, yes. That work pulls a permit with the City of Boulder Planning and Development Services and gets inspected. A like-for-like cosmetic refresh may not. Applications go through the city's online Customer Self-Service Portal. We pull the permit and schedule the inspections. Confirm current fees with the city.
My older Boulder home has one small bathroom. Can you make it work or add a second?
Both. In Mapleton Hill, Newlands, and Whittier the oldest homes were built with one small bath for the whole house. We either make that room work harder with a walk-in shower and a smarter layout, or we add a second bath in a former closet, a basement, or a Table Mesa pop-top, and handle the plumbing runs and the permit.
Does the Boulder energy code affect a bathroom remodel?
It can. The 2024 City of Boulder energy code favors electric equipment, so a heat-pump water heater is often the smart pick, and any exterior wall we open gets insulated to the required R-value. On a large project the code can require electric heating. We plan for it and ask you to confirm which rules apply to your project with the city.
How do you keep a Boulder shower from leaking?
Most bathroom callbacks are leaks from a shower that was never waterproofed correctly. We build showers with a real waterproof system behind the tile, not just backer board and hope, so the wall stays dry for the long run.
Are you licensed and insured?
Yes. JAC Enterprise is licensed and insured. License and insurance details come with your written estimate.
