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

Yes, for most projects. Simi Valley is in Ventura County and is its own city, so permits have nothing to do with Los Angeles. They are issued by Simi Valley Building and Safety at 2929 Tapo Canyon Road.

• Permits are required when plumbing or electrical is moved or added, walls are altered, or the layout changes
• A like-for-like fixture swap in the same position often does not require one
• Simi Valley offers over-the-counter plan check by appointment for straightforward projects, which can shorten the wait considerably compared with a full submittal
• If your tract has an HOA, its architectural review runs separately from the city process

We handle the submittal, the appointment, and the inspections so you do not have to learn the county process yourself.

Simi Valley is largely a 1970s through 1990s build-out, which means the homes are newer and larger than most of the Valley but the bathrooms have aged in a predictable way:

• Big master baths with a garden tub nobody uses, a small shower stall, and a separate toilet room. Removing the tub to build a proper walk-in shower is the single most requested change here
• Hard water is significant in this part of Ventura County, so we specify treated glass, quality valves, and finishes that will not spot within months
• Original builder-grade cultured marble tops and oak vanities that are structurally fine but date the room instantly
• Tract HOAs that require architectural review if anything on the exterior, including a new vent or window, is affected

Because these homes are newer, the plumbing behind the wall is usually copper rather than galvanized, which keeps surprises and costs lower than in older Valley neighborhoods.
