“I didn't think a bathroom could make that much of a difference until this one was finished. We kept the design pretty timeless with a walk in shower, porcelain tile, and a wood vanity, and it completely changed the feel of the space. It feels cleaner, more open, and just a lot more enjoyable to use every day.”

Northridge bathrooms date to the same post-war and 1950s–70s construction as the rest of the house: a hall bath with a tub-shower combo, a small primary bath added in a later remodel, galvanized supply lines and, on the slab-built ranch homes, drain lines under concrete. After five or six decades, most are ready for a full rebuild — new waterproofing, new supply and drain lines, proper ventilation and a layout that uses the room better. Because many Northridge houses carry post-1994 repair history, we also look at framing and subfloor condition carefully before tile goes down.
Many owners pair the bathroom with other work while the house is already open — a kitchen remodel, new flooring, or a panel upgrade — because one mobilization and one permit cycle is cheaper than three separate projects. We scope the bathroom on its own and as part of a combined project so you can compare honestly.
Northridge is part of the City of Los Angeles, so bathroom permits run through LADBS. We handle drawings, plan check, corrections and every inspection under one license, and you get a single written estimate covering the whole scope before work begins.

Read the cost guide- Hall bath refresh versus full rebuild
- When supply lines are galvanized and the pan is original, a surface refresh is money spent over failing infrastructure. We show you the condition of what is behind the walls at the estimate so the scope decision is informed.
- Walk-in shower in the primary bath
- Most Northridge primary baths were small afterthoughts. Reclaiming a closet or reworking the layout often allows a proper walk-in shower with a bench and niche; we lay out the options at full scale before you choose.
- Slab plumbing repairs
- Ranch homes on slabs sometimes need drain repairs that mean opening concrete. We locate lines with a camera before demolition so slab work is scoped in the estimate, not discovered mid-project.
- Waterproofing and subfloor condition
- Decades of slow leaks leave subfloor damage that is invisible until demo. We strip to framing, repair what we find, install full waterproofing membranes and flood-test pans before any tile is set.
- Timing around a one-bathroom household
- In a ranch home with a single working bathroom, downtime matters. We sequence demolition, plumbing rough and waterproofing tightly, set up a temporary wash station where practical, and give you firm dates for each stage before work begins. Most single-bath remodels keep the room offline for the shortest continuous window we can manage, and we tell you that window up front.
- Fixture and finish level
- A hall bath in a rental and a primary bath in an owner-occupied home call for different specifications. We price durable, mid-grade and premium fixture packages separately so the finish level matches how the room will be used and what the property justifies.
- Northridge is part of the City of Los Angeles; bathroom permits are issued by LADBS.
- Moving plumbing, altering ventilation or adding circuits requires a permit and inspections; in-place fixture swaps generally do not.
- Slab drain work is common in the ranch stock and is included in the permitted scope when needed.
- We prepare the drawings, submit for plan check, respond to corrections and schedule every inspection. Requirements change; we confirm them with LADBS before finalizing your estimate.
Timeline
Design and selections typically take a few weeks. Once demolition starts, a hall bathroom usually takes three to five weeks; a primary bath with layout changes or slab work runs longer. You receive a written schedule before we begin, and your coordinator confirms each LADBS inspection as it is booked.
