Condo bathrooms · Los Angeles
Condo bathroom remodels, planned around the building
In a condo, the bathroom is only half the project. The other half is the building: its approvals, its hours, its elevator, its plumbing and the neighbor directly below. We plan for both from the first visit.
What changes when the bathroom is in a condo
A house bathroom has one owner and one set of pipes. A condo bathroom shares walls, a floor-ceiling assembly and often a drain stack with other people's homes. That changes how the work is scheduled, what can move, and how much care goes into the layers nobody sees once the tile is down.
Los Angeles has a lot of these buildings: courtyard complexes from the 1950s and 60s, mid-rise concrete towers along Wilshire and the Westside, and newer podium buildings with wood-framed floors over a concrete garage. Each type behaves differently when you open up a bathroom, and each management company has its own way of approving and supervising the work.
We treat the building as a stakeholder. Before we price anything, we ask for the association's remodeling or alteration rules, look at what's behind the existing finishes where we can, and work out which parts of your wish list are simple and which ones depend on the building saying yes.
How a condo project runs
From the alteration request to the final walkthrough
Every association works differently, so treat this as the general shape rather than a fixed sequence. Where the HOA asks for something specific, their process wins.
Rules and records
You send us the HOA's remodeling rules, and any building drawings management can share. We read them before the design is set, not after.
Scope and drawings
We define what stays, what moves and what gets replaced, then prepare the scope description, drawings and material details the board or manager typically asks to see.
Building paperwork
Many buildings request certificates of insurance naming the association, contractor contact details and a deposit or signed agreement. We coordinate whatever paperwork your building asks for.
Permits where needed
Work that alters plumbing, electrical or structure often needs a permit. We confirm the current requirement with LADBS or your city's building department.
Build within the rules
Elevator bookings, protected corridors, permitted hours and water shut-off notices are scheduled into the plan from day one.
If you're still at the stage of working out what your association will and won't allow, our guide to HOA and building rules for condo bathrooms goes through the common approval questions in more detail.
Logistics
The practical side of working in a shared building
- Work hours
- Associations often limit noisy work to weekday daytime windows, and some restrict demolition to shorter blocks. Those limits set the pace of demo and tile cutting, so we build the schedule around them rather than hoping for exceptions.
- Elevator and corridors
- Where there's an elevator, buildings usually want it reserved and padded for deliveries and debris removal. We protect common-area floors and door frames along the route and keep the hallway clear at the end of each day.
- Parking and loading
- Street parking near many Westside and Mid-Wilshire buildings is tight. Delivery windows for tile, glass and vanity tops get planned so materials go straight up rather than sitting in a lobby or loading bay.
- Debris
- Old mortar-bed tile and cast-iron tubs are heavy. Buildings typically don't want construction waste in their bins, so removal is part of our scope, bagged and carried out along the approved route.
- Dust and neighbors
- Dust barriers at the unit door, negative-air where it helps, and cutting outdoors or in a designated area when the building allows it. Your neighbors notice the details, and so does the manager.
Plumbing in shared buildings
Stacks, risers and shut-offs
Most condo surprises live in the plumbing. These are the points we check early.
Stacked bathrooms and shared risers
Bathrooms in multi-story buildings are commonly stacked directly above one another, sharing a vertical drain and vent stack and sometimes supply risers. Those shared lines usually belong to the association, not to you, so any work that touches them needs the building's involvement.
Shut-off coordination
Some units have their own shut-off valves. Many older buildings don't, and replacing a shower valve means shutting water to a riser or a whole building. That takes advance notice to residents and a slot agreed with management, so we plan valve work as a scheduled event.
Old pipe at the connection points
In older LA buildings it's common to find galvanized supply lines and cast-iron drain pipe. We look at the condition where our new work ties in, because a clean new fitting on a corroded old pipe is where leaks start.
What can move, and what may not
Moving a toilet or shower drain in a wood-framed building may be possible within the joist direction. In a concrete building, drains are set into or below the slab, and post-tensioned slabs may limit coring or trenching altogether. We tell you early which moves look realistic and which depend on engineering or board approval.
Waterproofing and sound: the two things the unit below cares about
A slow leak in a house damages your own ceiling. In a condo it reaches someone else's, and the claim often lands on the owner who remodeled. We use a continuous waterproofing membrane on shower walls and pans, carried properly into the drain and up past the spray zone, and we flood-test shower pans before tile goes down where the assembly allows it.
Many HOAs also have rules about hard flooring and impact noise, commonly requiring an acoustic underlayment under tile and sometimes asking for product data sheets. Underlayment adds height, which affects door clearances and transitions, so we plan it into the floor build-up rather than squeezing it in later. If your association specifies a rating or product, that's what we follow.
For more on how the layers fit together, see our shower remodeling page.
Common condo bathroom projects
Tub out, shower in
The most frequent request in condos. It's usually workable, but the drain location, pan height and building rules all need checking first. Our tub-to-shower conversion page covers the build itself.
Same footprint, new everything
Keeping fixtures where they are is often the fastest route through approval, and it leaves most of the budget for tile, glass and a better vanity.
Making a small room work
Condo bathrooms are rarely generous. A wall-hung vanity, a recessed niche and a glass panel instead of a curtain can make a tight room feel planned. More on that in small bathroom remodeling.
What affects the cost of a condo bathroom
Condo work carries costs a house doesn't: slower daily output under restricted hours, protection of common areas, carrying debris out by hand, scheduled riser shut-offs, acoustic underlayment, and the time spent on building paperwork. None of these is dramatic on its own, but together they're why two bathrooms of the same size can price differently. Keeping drains where they are is usually the biggest single lever you control.
We explain how we put numbers together on our bathroom remodel cost and estimates page.
HOA rules, permit requirements and building policies vary and change. Read your association's current alteration rules and confirm permit requirements with LADBS or your city's building department before committing to a design.
Where we remodel condo bathrooms
West Hollywood and Santa Monica have a high share of condo and HOA-managed buildings, but we work in multi-unit buildings across our service area.
Condo remodeling questions
Do I need HOA approval to remodel my condo bathroom?
In most associations, yes, at least for anything beyond cosmetic changes. Replacing plumbing, moving fixtures, changing flooring and anything touching common elements usually needs written approval. Your CC&Rs and the building's alteration rules are the place to check.
Can you work with our building manager directly?
Yes. With your permission we coordinate elevator reservations, shut-off notices, insurance certificates and scheduling with management, and keep you copied so nothing gets decided without you.
Can I move the toilet in a concrete building?
Sometimes. It depends on how the drain runs, the slab type and what the association allows. Post-tensioned slabs may limit cutting entirely. We'd look at the existing conditions and any available drawings before promising a new location.
How long will my bathroom be out of use?
It depends on scope, permit timing, building hours and material lead times, so we give a schedule once the scope is set rather than a general figure. Restricted work hours usually make a condo job take longer than the same work in a house.
Will the neighbors hear the work?
Demolition and tile cutting are noisy. That's the reason many buildings limit hours. We keep the loudest work inside the permitted windows and give management notice of the noisiest days.

Converting a tub to a shower in a condo
Often yes, but a condo conversion hinges on HOA approval, what the slab allows at the drain, waterproofing over a neighbor, and how deep the floor really is.
