Fast, Reliable Bathroom Remodeling Across West Covina
A full bathroom remodel in West Covina typically runs $9,000-$28,000, with most projects quoted in writing before any demolition begins. If you’re living in a 1950s-1970s ranch tract home near Hollenbeck Street, Sunset Avenue, or the older streets off Azusa Avenue, your bathroom likely shares the same construction DNA as thousands of others across the city - original slab-on-grade foundation, stucco-over-wood-frame walls, and electrical systems that predate modern GFCI requirements. We dispatch crews to West Covina from our Los Angeles metro office, and we know what opens up when you pull the first piece of drywall in these homes. Call (626) 606-1081 to schedule your free written estimate.
Why Rowan Construction Group Pomona Is West Covina’s Preferred Bathroom Remodeling Company
We’ve delivered more than 4,000 projects since 2007, every one with a written price before work started and a documented photo record when the crew left. In West Covina specifically, that discipline matters because the housing stock is so uniform - when we open a bathroom in a 1962 ranch near Cameron Avenue, we already know the likely conditions: original 100-amp panel, possible slab settling from orchard-era fill, and framing that predates modern waterproofing standards.
Our crews are background-checked and uniformed; a live person answers calls 24/7. Under Clause 1 of The Haven Standard, the price is always written before anyone picks up a tool. We also offer a Free Second Opinion on any written estimate - bring us a competitor’s West Covina quote and we’ll review it line by line at no charge. The 365-Day Done Right Promise is printed on every contract, backed by a terms page, not an asterisk.
Grant Rowan built this system after seeing too many homeowners burned by verbal quotes and change-order shock. That hasn’t happened on our watch.
Our Bathroom Remodeling Services in West Covina

Full Bathroom Remodeling
A full bathroom remodel in West Covina means working within a narrow construction window - 1950s to 1975 - where original systems were never designed for modern loads. We strip to studs, assess the slab for level (orchard-fill settling is common), and write allowances for electrical, subfloor, and waterproofing surprises directly into the scope. Our Bathroom Remodeling team sources KraftMaid and Wellborn cabinets, Cambria and Caesarstone countertops, and Kohler or Toto fixtures from fifty-plus vetted brands. The quote is flat, with line-item allowances you can see before signing.

Walk-In Showers & Shower Remodeling
Walk-in shower installation in West Covina runs $4,500-$12,000. In these older ranches, we frequently find the original shower was built with no waterproofing membrane behind the tile - just stucco lath and hope. We install proper cement-board substrates with liquid-applied or sheet membranes, then finish with frameless glass enclosures where the layout allows. On a recent project near Hollenbeck Street, we opened a hall bath to find the subfloor spongy where a decades-old wax ring had failed and the copper rough-in had been sweated in behind stucco-over-wood framing that had never seen a modern waterproofing membrane. Inspection came first, we wrote allowances for the panel and the subfloor into the scope of work, and when the slab revealed fill settling we priced the leveling as a change order and got the homeowner’s written approval before a single tile was set. We finished with a frameless glass walk-in shower, KraftMaid vanity and Kohler fixtures, and walked the punch list with the inspector’s sign-off before final draw.

Tub-to-Shower Conversion
Converting an original West Covina tub to a walk-in shower runs $3,500-$10,000. The tub you’re removing was likely installed when the house was built, which means the drain location, valve height, and surrounding framing all reflect 1960s code - or pre-code practice. We price the plumbing rough-in move, the waterproofing upgrade, and any structural reinforcement in the written quote. If the slab needs leveling before tile goes down, that allowance is already in your contract. No work proceeds on a change until the change order is signed - that’s the discipline Haven acquired Rowan for, and the reason projects finish within a few percent of the number you agreed to.

Vanities, Tile & Fixtures
Vanity installation in West Covina runs $800-$3,000 depending on cabinet grade and plumbing complexity. We see a lot of original wall-hung sinks with inadequate blocking and no shutoff valves - minor fixes, but they add up if they’re not in the original scope. Tile work gets the same scrutiny: we check slab level before setting, because clay-soil cycling in the San Gabriel Valley means differential settling is a routine surprise once the old floor comes up. Our crews document substrate condition with photos before any material goes down. You get that record as standard, not an upgrade.

Common Bathroom Remodeling Problems We See in West Covina Homes

- Tiling over a shifted slab without confirming level. West Covina’s clay-soil cycling and orchard-era fill make differential settling a routine surprise once the old bath floor comes up. We check with a laser level before any tile is ordered, and we write a slab-leveling allowance into contracts where our initial probe suggests risk.
- Discovering the original 100-amp panel can’t support modern bath loads. GFCI outlets, heated floors, and proper exhaust fans draw more than 1960s electricians planned for. We inspect the panel during our initial walkthrough and price the upgrade as a written allowance, not a mid-project shock.
- Waterproofing that meets no membrane standard behind stucco-over-wood-frame walls. These walls predate modern California code, and the failure is invisible until the neighbor below or the adjacent bedroom shows the stain. We open, inspect, and replace with cement board and liquid membrane - documented with photos.
- Pulling a permit and finding the original copper rough-in is sweated behind inaccessible framing. Access matters for code inspection. We map the plumbing path before demolition and include access-panel installation in the scope where needed.

FAQs - Bathroom Remodeling in West Covina

It moves because 1950s-70s tract homes here share the same aging systems, and contractors can’t see through drywall. We control that movement by writing allowances into your contract for the conditions we suspect - slab level, panel capacity, subfloor integrity - then pricing any surprise as a signed change order before work proceeds. On a 1962 ranch near Hollenbeck Street, we found spongy subfloor and slab settling that required mudjacking; the homeowner had already seen the allowance line item, and the change order was signed before tile went down. Call (626) 606-1081 to schedule your free estimate and see how we write this protection into your scope.
Yes, if you’re moving plumbing, electrical, or walls - which describes most full remodels in West Covina. The city requires permits for fixture relocation, panel upgrades, and any structural modification. We pull permits as standard practice, schedule inspections at rough-in and final, and include the permit cost in your written quote. The inspector’s sign-off is required before final draw. Call (626) 606-1081 and we’ll confirm exactly what your project triggers.
It means we check level with a laser before ordering tile, and we may recommend mudjacking or self-leveling compound before installation. West Covina’s orchard-era fill beneath many slabs creates variable settling that gets worse with decades of clay-soil moisture cycling. Tiling over an unlevel slab guarantees cracked grout and failed waterproofing. We write a slab-leveling allowance into contracts where our initial assessment suggests risk, and we document the substrate condition with photos before any material goes down. Call (626) 606-1081 for a free assessment.
Yes, a tub-to-shower conversion runs $3,500-$10,000 and can be scoped as a standalone project. We still need to assess the drain location, valve height, and surrounding framing - all sized for 1960s practice - and we still need to bring waterproofing up to current standard. If the slab needs leveling or the panel needs upgrading to support a modern exhaust fan, those items are priced in writing before demolition. Call (626) 606-1081 to schedule your free written estimate.
We structure draws to match inspection milestones: deposit at contract signing, second draw at rough-in inspection pass, final draw after punch list completion and final inspection sign-off. No draw is due until the documented work is verified - you receive a photo record at every visit, and the inspector’s approval is required before we invoice for that phase. Under The Haven Standard, Clause 1 requires the full price in writing before work starts; the draw schedule is attached to that same document. Call (626) 606-1081 and we’ll walk through the exact schedule for your project.
