Why Penhallow Remodeling Riverside Is Claremont’s Preferred Bathroom Remodeling Company

Claremont homeowners deal with a layer of review that most Inland Empire cities don’t require. The Community Development Department looks at historical appropriateness on pre-1940 homes, and the tree preservation ordinance means a bathroom remodel touching an exterior wall can trigger an arborist review. We plan for that from the first site visit. Trevor Nash leads our team, and he has spent enough time in Claremont’s Craftsman and Spanish Colonial Revival homes to know what the reviewers will ask before they ask it.
Our technicians are background-checked and uniformed. When you book with us, you know who is walking through your door and when. A live person answers our phones 24/7, not a voicemail maze. We stock common fixture parts and rough-in materials so a shower valve replacement or vanity swap near the Village doesn’t stall waiting on a parts truck from Los Angeles.
We’re the Bathroom Remodeling team that puts the number in writing before demolition starts. If something fails inside the guarantee year, we return and fix it at no charge. That’s the standing rule, not a sales pitch.
Styles & brands we work with






Walk In Shower in Claremont
A walk in shower in Claremont usually runs $4,500 – $12,000 installed, depending on whether you’re converting a tub, reworking the drain location, or building a new curbless entry. In older Claremont homes, the bigger variable is structural: second-story bathrooms in 1920s Spanish Colonial Revival houses often have original wood framing that needs evaluation before a heavy glass panel goes in.
Wind-Load Framing for Second-Story Showers
Claremont sits in the San Gabriel foothills, and Santa Ana winds hit the north-facing walls hard. When a new shower changes an exterior wall opening or adds a larger window, the header and king studs have to meet current wind-rating code. We calculate that before we frame. A cheap quote that skips the engineering gets rejected at inspection and costs more to fix after the fact.
Tree Root Setbacks and Drain Placement
On one 1920s Spanish Colonial Revival near the Village, we opened a second-floor bathroom and found original wood framing cracked along the Santa Ana wind load path. The homeowner also had a mature coast live oak in the backyard with protected status. We replaced the load-bearing studs, moved the shower drain to satisfy the city’s tree-root setback, and installed a Kohler walk-in shower with a reinforced glass panel rated for Claremont’s wind exposure. The permit stayed open until inspection sign-off, and we closed the change order for the added rough-in work before drywall went up.
Bathroom Remodeling Companies in Claremont

Bathroom remodeling companies working in Claremont should hand you a written price before demo day, not a verbal range that balloons later. A full Claremont bathroom remodel runs $9,000 – $28,000, and a small bathroom remodel typically lands between $5,000 and $12,000. What pushes the number up here more than elsewhere is the city review layer: historical appropriateness on older homes, tree protection setbacks, and wind-load calcs on exterior changes.
What a Compliant Quote Includes
We line-item the wind-load calculation, the tree report or arborist review if the project touches a protected oak’s root zone, and the Community Development Department permit fees. If a quote doesn’t mention those for a pre-1940 Claremont home, the contractor hasn’t done this work here. You’ll pay for the change order later, after the subfloor is open.
Working With the Review Process
Claremont’s process is slower than Pomona’s or Upland’s. A bathroom remodel that changes an exterior wall or window on an older home often needs design review before the building permit gets issued. We sequence the work so framing and rough-in happen only after approvals, which keeps the job moving instead of leaving a torn-up room waiting on a hearing date.
Trusted Brands We Service in Claremont
We install fixtures and surfaces from brands that carry their own warranties alongside our 365-Day Done Right Promise. For Claremont showers, we use Kohler and Moen valves and heads. For vanities, we work with KraftMaid and Wellborn cabinetry. Countertop work pulls from Cambria, Silestone, and Caesarstone quartz lines. We also install Belgard products where outdoor elements tie into a bathroom remodel, like a patio drainage channel that meets the new shower drain line. Our Riverside location keeps common replacement parts in stock so most Claremont jobs don’t wait on distributor lead times.

AfterCommon Bathroom Remodeling Problems We See in Claremont Homes
- Original wood framing cracked from heat and Santa Ana wind. Inland Southern California’s dry heat and seasonal winds cause wood to shrink and split over decades. In pre-1940 Claremont homes near the Village, that means second-story bathroom walls often need structural repair before tile goes up.
- Stop-work orders from skipped historical review. Contractors who enlarge a window on a 1920s Craftsman without city approval get a stop-work notice and doubled permit fees. We handle the Community Development Department review before cutting the opening.
- Plumbing routed under protected oak canopies. A shower drain or vent stack placed inside a mature oak’s root zone can trigger a retroactive tree report and a costly re-route after the subfloor is poured. We check the tree map at the estimate stage.
- Framing rejected for missing wind-load calcs. Claremont’s foothill zone requires a header sized for current wind-rating code when a new exterior wall opening goes in. Skipping the calculation means an inspector rejection and a tear-out to reframe.

FAQs About Bathroom Remodeling in Claremont
Claremont requires review for historical appropriateness on pre-1940 homes when an exterior wall or window changes, plus a building permit with current wind-load calculations for the foothill zone. For a bathroom remodel this means submitting plans before cutting any opening, and on some properties getting a design review approval before the building permit is issued. Call (341) 895-1170 and we can walk you through what applies to your block.
Any new exterior wall opening has to carry a header sized for current wind-rating code, and the glass panel should be rated for the wind exposure. We calculate that load before framing, and the inspector checks it. If the framing was put in without the calc, the inspector will reject it and you’ll pay for a tear-out. Our written quotes include the wind-load calculation as a line item.
Claremont’s tree preservation ordinance protects mature oaks and other designated trees. If your shower drain, vent stack, or any foundation work falls inside a protected tree’s root zone, the city requires a tree report. Without it, you risk a stop-work order and a plumbing re-route after the subfloor is poured. We identify the risk at the estimate so the line item is in the first number, not a change order.
Yes, in most cases. We work around original plaster where the wall is sound, and open only the sections that need new supply lines, drain lines, or blocking for grab bars and shower fixtures. The code cares about the plumbing and the framing, not whether the wall finish is original. For a second-story bath off Claremont Boulevard or Indian Hill, the framing is usually the bigger variable.
An insurance adjuster is much less likely to deny a water or wind claim when the bathroom remodel shows a closed permit with passed inspections, especially for structural and drain work. The record proves the work met current code. That matters in Claremont, where older homes with original plumbing and framing get extra scrutiny. We hold permits open until final sign-off and you get the close-out paperwork.
