5 Common Mistakes to Avoid When Converting a Bathtub to a Shower in Dover, NH

Center Barnstead, United States – July 30, 2025 / Cloud 9 Tubs LLC /

Dover, NH — Converting a bathtub to a shower has become a popular remodeling choice among homeowners in Dover, NH, looking to improve safety, convenience, and space in their bathrooms. However, even small mistakes during this process can lead to costly repairs or disappointing results.

Cloud 9 Tubs LLC, a leading bathroom remodeling company in Dover, highlights the five most common mistakes homeowners should avoid during bathtub-to-shower conversions. The goal is to help residents make informed choices and get better results from their investments.

Common Tub-to-Shower Conversion Mistakes and How to Avoid Them

Plumbing Layouts Can’t Be Ignored

One of the most overlooked details is the plumbing configuration. Many bathtubs have smaller drains, while showers require larger ones to keep up with water flow. According to most plumbing codes, showers typically require a minimum 1½-inch drain, though many codes specify 2-inch drains for optimal performance, especially when converting from bathtubs that use 1½-inch drains. Showers also need a quarter-inch pitch per foot to move water efficiently. Skipping this detail can lead to standing water, slow drainage, or even mold and rot behind the walls.

Choosing the Wrong Shower Base

Not all shower pans fit into the space left by a removed bathtub. Prefabricated pans are often available in standard sizes that don’t match older tub footprints. That can leave gaps or require unnecessary changes to walls and plumbing.

To address these fit and alignment challenges, Cloud 9 Tubs uses acrylic shower bases that are available in a range of sizes and can be trimmed or custom-fit to match existing layouts. Acrylic bases are lightweight, mold-resistant, and easier to clean than tile, which makes them a smart choice for New Hampshire homes with changing humidity and temperature. Their flexibility helps avoid costly structural changes while still providing a durable, reliable foundation for a new shower.

Waterproofing Done Right

Many water damage issues happen behind the walls. A common mistake is installing a water-resistant wallboard without a full waterproof membrane on top. To avoid long-term problems, showers need sealed corners, joints, and shelves to prevent moisture from getting into the wall framing.

Without proper waterproofing, mold can begin to form in as little as 24 to 48 hours after water exposure. Cloud 9 Tubs follows national best practices to ensure each tub-to-shower conversion includes a tested waterproofing system before finishing walls.

Planning for Functionality, Not Just Looks

A tub-to-shower conversion should make the bathroom easier and safer to use, especially for those planning to stay in their homes long-term. Low-threshold bases, wider entries, and non-slip floors make showers safer and easier to use every day. For older adults, built-in seating and handheld showerheads add convenience and flexibility.

Cloud 9 Tubs installs grab bars for added safety, and if they aren’t installed right away, walls can be prepared to support grab bars later. Reinforcing the framing during installation makes it safer and simpler to add these features later.

Avoiding DIY Mistakes

Do-it-yourself tub-to-shower conversions may seem cost-effective, but even small errors can cause big issues down the line. Common DIY problems include poor slope, leaky doors, and misaligned drains. Structural issues, like blocked joists or mismatched framing, often go unnoticed until too late.

Working with experienced professionals reduces those risks. Cloud 9 Tubs manages the full process to deliver showers that meet code, perform well, and stand up to years of use.
