A 200-room mid-scale hotel in Houston needed a full bathroom renovation. The property was 18 years old and operating under a major brand flag. The bathrooms were original to the building: fiberglass tub-shower combinations with tile surrounds, laminate vanity tops, and acrylic sinks. By year 18, the fiberglass was cracked in 40 rooms, the laminate was delaminating in over 60, and the tile grout was permanently stained or missing in nearly every bathroom.
The owner had two options. Shut down floors one at a time and renovate over six to eight months, or find a faster solution. The brand required all bathrooms to be in sellable condition within 45 days of renovation start. Any room out of service longer than that would lose its brand flag for that room until it was restored.
The owner chose the second option. They called Wiselink.
The renovation scope was straightforward on paper: remove all existing tub-shower units and replace with walk-in showers. Replace vanity tops and sinks. Replace faucets, showerheads, mirrors, lighting, and toilet accessories. Fresh paint and new flooring.
The challenge was the timeline. Forty-five days to complete 200 rooms. That meant an average of 4.5 rooms per day. With tile showers, the industry standard for a tub-to-shower conversion is two to three days per room. At that pace, two crews working seven days a week could complete roughly 45 rooms in 45 days. Not 200.
The hotel's general manager was blunt about the math. "We could not lose 155 rooms of inventory for an extended period," she said. "The revenue loss alone would have killed the business case for the renovation."
The solution had to be faster, more predictable, and less dependent on skilled trade availability.
Wiselink proposed cast marble shower systems with offset drain renovation pans for all 200 rooms. The offset drain design allowed the new shower drain to align with the existing tub drain location, eliminating the need to relocate plumbing in the concrete slab.
The panels were specified in a 3x6 subway pattern in white gloss finish. This matched the hotel's brand design standards while providing a clean, contemporary look that would age well.
The vanity tops were cast marble with integral sinks, also in white. No seams between sink and countertop. No grout lines to collect dirt. No sealing required.
The owner reviewed samples at Wiselink's showroom and approved the specification in one visit. "The color match was perfect. The feel of the surface was better than the fiberglass we were replacing. And the price made the financials work," the GM said.
The renovation was planned in four phases of 50 rooms each. Rooms were taken out of service sequentially — one floor at a time — so the hotel could continue operating at 75% occupancy throughout the project.
Phase 1: Floors 5-6 (50 rooms). Rooms out of service on Monday morning. By Friday, all 50 showers were installed. Painting, lighting, and accessories were completed over the weekend. Rooms were back in service on Monday. Five days, floor to finish.
Phase 2: Floors 3-4. Same sequence. Five days.
Phase 3: Floors 2 and 7. Six days — one room had a subfloor issue that required a 24-hour repair.
Phase 4: Floor 8. Two days.
Total construction time for all 200 rooms: 18 days.
The tile bid had estimated 45 days. The actual cast marble installation took 18 days.
The owner obtained competitive bids from three tile contractors. The lowest tile bid for the full scope of work was $620,000. That included demolition, waterproofing, tile installation, grouting, sealing, and vanity replacement. The highest tile bid was $785,000.
The Wiselink cast marble solution, installed, came in at $415,000.
Cost breakdown:
Savings vs. the lowest tile bid: $205,000 — a 33% reduction.
The owner noted additional savings beyond the direct construction cost. Rooms were back online 27 days earlier than the tile schedule would have allowed. At an average daily rate of $119 and 78% occupancy, each room generates roughly $92 per night in revenue. Twenty-seven days of additional revenue across 200 rooms: $496,800 in gross revenue that would have been lost under the tile schedule.
When the owner presented these numbers to their regional brand office, the response was immediate approval for the same approach at two other properties in their portfolio.
The hotel tracked guest satisfaction scores for bathrooms before and after the renovation. Pre-renovation bathroom satisfaction scores averaged 3.6 out of 5 on the brand's guest survey. Post-renovation scores averaged 4.7 out of 5.
The most common guest comments were:
Two guests commented that the shower walls looked like "real marble." The GM noted that several guests had asked whether the hotel had upgraded to a luxury tier.
Two years after installation, the property reported zero maintenance issues related to the shower systems. No leaks. No cracks. No grout repairs (because there is no grout). No stain complaints.
The hotel's head of engineering compared the maintenance requirements to the previous tile and fiberglass units. "With the old bathrooms, we had at least one grout repair every month. Sometimes a cracked tile. Sometimes a leak at the tub spout. With the new cast marble units, I do not get calls about bathroom issues. It has been two years, and I have not had a single shower-related maintenance ticket."
The housekeeping team reported that the cast marble surfaces were easier to clean than the previous fiberglass and tile. The non-porous surface did not hold soap scum as aggressively. A quick wipe with a mild cleaner restored the gloss. The integral sink eliminated the caulk seam that collected mildew between the old laminate top and drop-in sink.
Three factors made this project successful.
First, the product choice. Cast marble eliminated the variables that cause schedule overruns in tile installation — waterproofing, curing time, and skilled labor availability. The installation team did not need to be tile specialists. They were trained on cast marble installation in half a day.
Second, the planning. The four-phase approach kept the hotel operational throughout the renovation. Revenue loss was minimized. Guest disruption was contained to one floor at a time.
Third, the partnership. Wiselink coordinated panel production to match the renovation schedule. Panels arrived on site in batches, just-in-time for each phase. No storage issues. No damaged material from extended job site exposure.
Q: How did the offset drain work with the existing tub drain location?
A: The cast marble pan was molded with the drain offset by up to 6 inches from center. This allowed the new shower drain to connect to the existing waste line without breaking concrete. The adapter kit included a 90-degree elbow and Fernco coupling for a simple connection.
Q: Were there any rooms with out-of-square walls that caused problems?
A: Two rooms required shimming on one wall. The installer used composite shims behind the panel to correct a 3/8-inch gap. The panel covered the gap without visible distortion. The installation guide included this scenario.
Q: How long did the hotel wait after installation before using the showers?
A: The adhesive cured in 4 hours. Showers were usable the same day. No extended curing time was required.
Q: Would the owner do it again?
A: Yes. The property is planning the same approach for two additional hotels. The GM stated: "I would not go back to tile. The numbers do not support it, and the maintenance savings are too good to ignore."
Q: What was the warranty on the cast marble systems?
A: Wiselink provided a 10-year warranty on the gel coat against manufacturing defects. No claims were made in the first two years.
