We’ve completed over 4,000 projects across seven trades, every one with a documented photo record and a signed scope of work. In Pomona specifically, we regularly work with the older housing stock north of the 10 Freeway - homes built from the 1940s through the 1980s with galvanized plumbing, inadequate ventilation, and bathrooms that were functional fifty years ago but don’t match how families actually live now. The clay-heavy soils in this part of the Pomona Valley also create subtle foundation shifts that show up first in bathroom tile and door frames. We check for that during our initial walkthrough, photograph what we find, and explain what it means for your project timeline and price.

Grant Rowan has led this operation since founding it in 2007. Our crews are background-checked and uniformed, and a live person answers our phones 24/7. The 365-Day Done Right Promise applies to every bathroom remodel we take on in Pomona - if it’s not done right, we make it right, with the guarantee printed on your contract, not hidden behind an asterisk.

What Our Bathroom Remodeling Service Includes

Full Bathroom Remodeling

A full bathroom remodel strips the room to the studs and rebuilds it with new plumbing, electrical, fixtures, and finishes. In Pomona, we most often see this need in the original bathrooms of postwar ranch homes and the 1960s tract housing in neighborhoods like Lincoln Park and Mayfair - spaces with 32-inch showers, single sinks, and no exhaust fans. We handle permit pulling with the City of Pomona Building & Safety Division, coordinate inspections, and deliver a flat written price that includes every line item from demolition debris haul-away to final caulk.

Walk-In Showers & Shower Remodeling

Walk-in shower remodeling replaces tub-shower combos or outdated stall showers with curbless or low-threshold entries that are easier to access and clean. We install Schluter-Kerdi or Wedi waterproofing membranes - bonded sheet membranes that seal the substrate before tile goes on, which matters in Pomona’s hard water environment where moisture intrusion behind tile is the most common cause of hidden damage. Our written quote specifies the membrane brand, the tile layout pattern, and the grout type so you know exactly what you’re paying for.

Tub-to-Shower Conversion

Tub-to-shower conversion removes an unused bathtub and installs a shower in its footprint, often gaining 6 to 12 inches of usable floor space in the process. This is one of our most requested services in Pomona’s smaller 1950s and 1960s bathrooms, where the original 5-foot tub dominates a room that’s barely 40 square feet total. We check the existing drain location - whether it’s centered or offset - and price the plumbing modification separately so there’s no surprise if the drain needs to move. The typical tub-to-shower conversion in Pomona runs $3,500 to $10,000 depending on wall tile height and fixture selection.

Vanities

Vanity replacement updates storage, counter space, and the overall look of the bathroom without the cost of a full remodel. We source from KraftMaid and Wellborn cabinet lines - both offer semi-custom sizing that matters in Pomona’s older homes where wall lengths are rarely standard 24-inch or 36-inch increments. Our quote includes the vanity, countertop (quartz, solid surface, or laminate with specific brand and color named), faucet rough-in if needed, and connection to existing supply lines. If your old vanity was caulked to a textured wall, we price the wall repair and skim-coat separately so the finish is smooth, not wavy.

Tile & Fixtures

Tile and fixture updates refresh a bathroom’s appearance and function without moving walls or plumbing. We install porcelain, ceramic, and natural stone tile with specific attention to the substrate preparation - in Pomona’s climate, with summer temperatures above 90 degrees and winter nights in the 40s, the thermal cycling can stress poorly bonded tile over time. We use modified thin-set mortars rated for the application and specify expansion joints at changes of plane. Fixtures are sourced from Kohler and Toto lines, with model numbers written into the quote so you can compare prices independently.

Small Bathroom Remodels

Small bathroom remodeling - typically powder rooms or guest baths under 40 square feet - requires careful space planning to avoid a cramped result in Bathroom Remodeling in Montclair and nearby areas. In Pomona’s denser neighborhoods near downtown and the Cal Poly campus, these are often the only bathrooms on the main floor of converted duplexes or accessory dwelling units. We specialize in wall-hung toilets and corner vanities that reclaim floor area, and we specify compact fixtures that meet California WaterSense standards for the 1.28 gpf flush requirement. Small bathroom remodels in Pomona generally range from $5,000 to $12,000.

Walk-In Shower Installation

Walk-in shower installation creates a new shower where none existed or expands a closet or unused corner into a functional bathing space. This requires new plumbing rough-in, waterproofing, and often structural assessment of the floor framing to confirm it can support a mortar bed or prefabricated pan. In Pomona’s hillside homes near Phillips Ranch and the northern slopes, we also evaluate drainage slope and whether a sewage ejector pump is needed if the new shower sits below the main sewer line. Walk-in shower installation typically runs $4,500 to $12,000 in this market.

Brands We Service for Bathroom Remodeling

Our material sourcing runs through fifty-plus vetted brands, and we name the specific manufacturer and product line in every written quote. For bathroom remodeling in Pomona, we regularly specify Kohler fixtures - their Devonshire and Archer lines are widely available, parts are stocked locally, and the valve platforms are backward-compatible, which matters for future repairs. We’ve installed hundreds of Kohler pressure-balance valves and can show you the trim options before you commit, so you’re not guessing from a catalog photo.

We also work with Toto for clients who want the Washlet-integrated toilets or their Drake and Ultramax II models with the Tornado Flush system. Toto’s California compliance is straightforward - they’re based in the state and have engineered for our water restrictions for decades - and we can source through standard distribution without the markup of special-order freight. For prefabricated modular elements in ADU or addition projects, we’ve installed Mighty Buildings units and understand their plumbing chase configurations and connection points. Whether you have a specific brand preference or want us to recommend based on your budget and the fixture schedule in your quote, we can help. Every brand name in your proposal is one we’ve installed before and can document.

Signs You Need Bathroom Remodeling Right Now

• Soft or stained drywall near the tub or shower. This indicates moisture has breached the tile or caulk seal and is degrading the wallboard behind it. In Pomona’s dry climate, homeowners often miss slow leaks because the moisture evaporates quickly from the surface - but the damage continues inside the wall, breeding mold and weakening studs. We use a moisture meter during our free estimate to map the affected area and photograph the readings.
• Cracked floor tile or grout that won’t stay clean. Cracking suggests movement in the subfloor or an inadequate mortar bed; perpetually dirty grout means it’s porous or failing and is no longer protecting the edges of your tile. Both are common in Pomona bathrooms with original installations from the 1970s and 1980s, when plywood subfloors were often too thin for ceramic tile loads.
• Galvanized steel supply pipes with reduced water pressure. If your home was built before 1965 in Pomona, you likely have galvanized plumbing that’s corroding from the inside. The first sign is often low hot water pressure at the shower, because the hot line corrodes faster. A remodel is the practical time to replace accessible horizontal runs with PEX or copper - we price this separately so you can decide based on the pipe condition we document.
• No exhaust fan, or a fan that vents into the attic. California code now requires exhaust ventilation to the exterior, and Pomona’s summer humidity spikes - especially during monsoonal flow in August and September - make this a functional issue, not just a code one. We calculate the required CFM based on room volume and specify ducted venting through the roof or gable end, with the routing shown on your written scope.
• The layout doesn’t match how you use the space. This is the most common reason we hear from Pomona homeowners: a single vanity when two people get ready simultaneously, a tub that hasn’t been used in years, or a toilet visible from the hallway through a poorly placed door. Remodeling for function rather than repair often yields the highest satisfaction, and we draw the proposed layout to scale as part of your free estimate so you can test the circulation before construction starts.

Our Bathroom Remodeling Process - Step by Step

1. 1
   On-site assessment and measured drawings. We visit your Pomona home, photograph the existing conditions with a dated photo record, measure every surface, and note plumbing locations, electrical panel capacity, and any structural conditions that affect the scope. You’ll receive these photos as part of your project file, whether you hire us or not.
2. 2
   Written line-item quote with flat price. Within 48 hours, we deliver a written proposal that names every material brand and model, every labor line, and every permit or inspection fee. The total is a flat price - not an estimate that drifts upward. Under Clause 1 of The Haven Standard, this written price precedes any work; no tool is picked up until you’ve signed the scope and the price.
3. 3
   Permit application and material ordering. We pull permits with the City of Pomona Building & Safety Division and schedule inspections at rough plumbing, electrical, and final. Materials are ordered with confirmed lead times written into the project schedule - we don’t start demolition until critical-path items are in hand or have guaranteed delivery dates.
4. 4
   Construction with documented daily progress. Our background-checked, uniformed crew works on your project with a dedicated lead carpenter who reports daily. The photo record continues through construction: substrate conditions before waterproofing, plumbing pressure tests, electrical rough-in, and finish installation. You receive these images in a shared folder as work progresses.
5. 5
   Final inspection, walkthrough, and warranty documentation. After the city passes final inspection, we conduct a walkthrough with you using a punch list we both sign. Any items are scheduled for correction within 72 hours. You receive the signed completion certificate, the 365-Day Done Right Promise in writing, and the full photo archive of your project. If something isn’t right during that first year, we make it right - the promise is printed on your contract, not implied.
