Bathroom Remodeling in Simi Valley, CA

Simi Valley Bathrooms Ready for a Practical, Lasting Upgrade

Simi Valley families in Wood Ranch, Big Sky, and Bridle Path are ready to replace dated garden tubs and almond tile with walk-in showers, double vanities, and durable finishes that hold up through years of family use — Caspi Construction makes it happen on budget and on schedule.

The 1980s through early 2000s suburban homes that define Wood Ranch, Big Sky, and Bridle Path were built with generous bathroom footprints — large master suites, separate tub and shower areas, and double vanities that felt premium when the homes were new. Two decades later, those same bathrooms show every year of use: pink and almond tile that stains, garden tubs that no family member has filled in years, laminate vanity tops that have delaminated at the seams, and single-globe vanity lighting that makes every bathroom look the same shade of tired. A bathroom remodel in Simi Valley at this housing vintage is about replacing everything that has failed with materials that are genuinely built to last — large-format MSI porcelain that doesn’t show stains, walk-in showers that two people can use simultaneously, and double-sink vanities that solve the morning routine bottleneck. Caspi Construction is a licensed Simi Valley bathroom renovation company (CSLB #1091631) with a 4.9★ rating across 153+ bathrooms. Permits go through the City of Simi Valley — not LADBS — and we manage that process entirely.

Garden Tub Removal & Walk-In Shower Conversion

Replacing an unused Simi Valley garden tub with a walk-in shower is the most impactful single change available in a master bathroom renovation. We demo the platform and tub, reconfigure the drain and supply plumbing under City of Simi Valley permit, waterproof the new shower walls with a professional membrane system, and tile with large-format MSI porcelain. A frameless glass enclosure — typically a fixed panel and pivot door — completes the conversion and opens the bathroom visually.

Double Vanity & Countertop Upgrade

Adding or replacing a double vanity in a Simi Valley master bath solves one of the most common household frustrations in homes with two adults sharing a bathroom. We design vanity configurations that fit your bathroom's specific dimensions, specify Kohler undermount sinks in coordinating finishes, install MSI quartz countertops, and add LED mirror medicine cabinets above each sink for task lighting and hidden storage.

MSI Large-Format Tile Installation

Large-format MSI porcelain — 24x24 on the floor, 12x24 or 24x48 on the shower walls — is our standard specification for Simi Valley bathroom renovation projects. The larger format reduces grout lines, making the tile easier to maintain and the room feel more open. MSI's stone-look collections deliver the appearance of natural marble or limestone without the sealing requirements, which makes them particularly practical for active family bathrooms.

Full Lighting Redesign

Replacing dated vanity lighting with a layered LED system — individual sconces flanking the mirror, recessed fixtures on a dimmer for ambient light, and optional under-vanity LEDs — transforms how a Simi Valley bathroom feels throughout the day. We coordinate the new lighting layout as part of the overall renovation design and manage the City of Simi Valley electrical permit when new circuits are involved.

Recent Bathroom Projects Near Simi Valley

Project 1 — Wood Ranch Master Bath Transformation

A 1994 Wood Ranch home had a master bathroom with a large garden tub platform that dominated the center of the space — taking up square footage that made the shower feel cramped and the rest of the room cluttered. The homeowner wanted a full transformation within a $32K budget. We demolished the tub platform, built a 54x36-inch walk-in shower with 24x48 MSI Statuario Grey porcelain on all walls, a Kohler Forte rain head in brushed nickel, and a frameless glass door with a fixed side panel, replaced the single-sink vanity top with a 60-inch MSI White Attica quartz top hosting two undermount Kohler Verticyl sinks with matching brushed nickel faucets, retiled the floor in 12x24 cool grey MSI porcelain, and replaced the single light bar with LED sconces and recessed overhead lighting. The City of Simi Valley permits for plumbing and electrical modifications were managed throughout, and the project was completed in six weeks.

Project 2 — Big Sky Secondary Bathroom Refresh

A Big Sky homeowner had a secondary bathroom shared between two school-age kids — an original tub-shower combo with a plastic surround that had cracked along the bottom seam, a pedestal sink with no storage, and almond-colored wall tile that the family found impossible to keep looking clean. The goal was a practical, durable renovation within a $18K budget. We replaced the plastic surround with MSI Calacatta Gold porcelain tile in a 4x12 stacked pattern, installed a 36-inch floating vanity in a cool white finish with an undermount RUVATI sink and matte black Kohler faucet, retiled the floor in a 2-inch black-and-white hex mosaic, replaced the toilet with a Kohler Highline, and added a horizontal LED mirror. No plumbing was moved, and no City of Simi Valley permit was required for the cosmetic scope. Completed in two and a half weeks.

Project 3 — Bridle Path Master Bath Full Gut

A Bridle Path home had a master bathroom in the original condition from when the house was built in 1988 — pink four-inch wall tile, a garden tub that was never used, a dated oak vanity with a two-sink laminate top, and a separate shower that was barely large enough for one person. The homeowner wanted the full renovation. We gutted the entire bathroom, converted the tub space to a 60x48-inch walk-in shower with MSI Calacatta Laza porcelain, a Kohler DTV+ rain head and hand spray system, and a frameless glass enclosure, installed a new 72-inch floating double vanity in a warm grey finish with Kohler Verticyl sinks and polished chrome faucets, added electric radiant heating under the new 12x24 MSI porcelain floor, and installed a full recessed lighting plan on dimmers. City of Simi Valley permits covered all plumbing, electrical, and mechanical work. The bathroom renovation in Simi Valley was completed in eight weeks.
