Pricing depends on the size of the room, whether the layout changes, and the finishes you choose. As a general guide for the Los Angeles area:

• Guest or hall bathroom refresh: roughly $18,000 to $30,000
• Full mid-range remodel with new tile, vanity, and fixtures: roughly $30,000 to $55,000
• Master suite or spa-level build with custom tile and glass: $60,000 and up

Moving plumbing, converting a tub to a curbless shower, or discovering old pipes behind the wall will push a project toward the higher end. We give you a written, itemized estimate after the free in-home consultation so there are no vague allowances or surprise line items later.

Most standard bathrooms take three to five weeks of on-site work. A master bath taken down to the studs, or one where we relocate plumbing, usually runs five to eight weeks.

• Design, material selection, and permit approval happen before demolition and typically add two to four weeks
• Custom orders such as slab countertops, frameless glass, and specialty tile need lead time, so we order them early
• You get a written schedule at the start and a heads-up any time something shifts

If it is your only bathroom, tell us during the consultation. We can sequence the work to shorten the days you are without a working shower.

Yes. KN Remodeling is a licensed and insured California contractor with more than 30 years of remodeling experience, and we carry liability coverage and workers' compensation on every job.

• Your project is run by one dedicated project manager from consultation through final walkthrough
• Plumbing and electrical work is performed by licensed trades and signed off by the city inspector
• You see the same core crew day to day rather than a rotating cast of subcontractors
• Workmanship is backed by our warranty, and manufacturer warranties on fixtures are handed over at closeout

In most cases, yes. Chatsworth is part of the City of Los Angeles rather than a separate city, so there is no local city hall for permits. Permits are issued by the Los Angeles Department of Building and Safety, and the counter that serves this part of the Valley is the Van Nuys Development Services Center at 6262 Van Nuys Blvd.

• You need a permit any time plumbing or electrical lines move, walls are altered, or the layout changes
• A like-for-like fixture swap in the same position often does not require one
• Properties on the rocky slopes toward the Santa Susana foothills can draw extra review when the work touches the structure
• Larger equestrian lots north of Devonshire that run on septic need the system checked before a fixture is added

We pull the permits, book the inspections, and keep the records so your file is clean when you eventually sell.

Much of Chatsworth was built out between the 1950s and the 1970s, with larger lots and horse properties mixed into the tracts. Here is what we run into most often once the walls are open:

• Hard water is a real issue in this part of the west Valley, so we specify treated glass and fixtures that will not scale up within a year
• Galvanized supply lines and cast iron waste lines that are worth replacing while access is easy
• Plumbing and framing repairs made quickly after the 1994 Northridge earthquake that were never brought up to current code
• Exhaust fans vented into the attic rather than through the roof, which shows up later as mildew on the ceiling

Our Woodland Hills office is a short drive from Chatsworth, so we can be on site the same day if something unexpected turns up mid-project.
