GAINESVILLE, GA – Shower systems in multifamily and hospitality properties require precise installation, and errors made during planning or execution can result in costly issues that are not immediately visible. They can impact resident safety, unit availability, and the long-term performance of the building.
Mincey Marble Manufacturing, based in Gainesville, Georgia, is issuing an advisory to property owners, developers, and on-site management teams to highlight installation mistakes that can compromise the long-term durability of shower systems and lead to portfolio-wide repair costs.
“Many of the failures we see stem from details that were missed early in the installation process,” a company representative said. “Components such as shower pans, drainage systems, and waterproofing transitions must be correctly integrated, because even small gaps can allow moisture to penetrate behind finished surfaces and cause progressive damage over time.
“In a stacked apartment building or hotel, that kind of gradual failure typically does not remain confined to a single unit.”
Inadequate site preparation is a major factor contributing to these failures. When underlying structures such as wall studs and subfloors are not properly evaluated, existing unevenness or damage can compromise the stability of the entire system once installed. Residual materials from previous work, including adhesives or debris, can also interfere with proper bonding and create weak points within the finished assembly.
On large-scale projects where dozens or hundreds of units are completed under tight renovation schedules, this kind of oversight can create predictable points of failure in the future.
Waterproofing WHEN USING TILE must be applied as a continuous barrier across all required surfaces. Any gaps in coverage allow moisture to reach underlying materials, where deterioration can occur without visible warning signs. Corners, joints, and transitions require reinforced application due to increased exposure to water.
In multi-unit buildings, water intrusion through these gaps can spread to adjacent units and lower floors. This can significantly increase the scope of remediation by the time the issue is identified.
Drainage performance depends on an accurate slope and the correct placement of the drain assembly. If water does not flow efficiently toward the drain, it can collect in low points and contribute to surface wear and hygiene concerns over time. DRAINS ALSO SHOULD BE REGULARLY MAINTAINED TO REMOVE ANY BLOCKAGES. For hospitality and multifamily operators, standing water also drives up complaints from guests and residents and the kind of recurring maintenance calls that erode operating margins.
Wall installation requires consistent alignment across all panels, as minor deviations in positioning can create uneven surfaces. All joints and transitions require sealing with materials suitable for high-moisture environments. Inconsistent application or incorrect product selection can allow water intrusion behind finished surfaces, leading to mold concerns, premature wall replacement, and extended unit downtime between residents or guests.
DEPENDING ON THE MATERIAL USED, INSTALLATION SHOULD BE PERFORMED BY AN EXPERT IN THAT MATERIAL. A TILE INSTALLER SHOULD NOT INSTALL A FIBERGLASS UNIT, AND A PLUMBER SHOULD NOT INSTALL CAST MARBLE WALL PANELS. INSIST ON A REPUTABLE INSTALLER, OR GET THEM TRAINED IN THE PRODUCT CATEGORY. INEXPERIENCE CAN LEAD TO INSTALLATION ERRORS THAT AFFECT INSTALLATION OF SUBSEQUENT PRODUCTS, AND THEY CAN BECOME COSTLY WHEN NEEDING TO ORDER ADDITIONAL REPLACEMENT MATERIAL.
Finally, installation must not be rushed, and the steps involved should not be performed out of order. There must be enough time for adhesives and sealants to cure. In large multifamily and hospitality projects where renovation timelines are compressed, cutting corners on cure time often leads to defects that emerge months later as warranty issues and expensive call-backs throughout the property.
A controlled and methodical installation process ensures that each stage is completed properly, which reduces the likelihood of hidden defects and improves the overall stability of the system.
