Everything You Need to Know About Roll-In Shower Pans: A Comprehensive Guide

More homeowners across Dover, NH, are choosing to convert their bathtubs into showers. In homes where a traditional tub is no longer suiting the daily needs, it’s a practical way to make bathrooms more accessible, reduce upkeep, or make better use of space. But while a bathtub-to-shower conversion can bring real improvements, it’s not without challenges. If certain details, like drainage, waterproofing, or structural compatibility, are overlooked, the upgrade may not last as long or perform as well as expected. These avoidable issues are usually caused by rushed or incomplete installations. At Cloud 9 Tubs LLC , we take a practical, detail-oriented approach to getting tub-to-shower conversions right the first time. We’re based locally and understand the specific conditions and layouts common in homes across the region. Our work is built on clear planning, durable materials, and attention to detail. So homeowners can enjoy long-term results without second-guessing the process. In this article, we’ll walk through five of the most common mistakes we see during tub-to-shower conversions and explain how to avoid them for a smoother, longer-lasting outcome. Mistake #1 – Overlooking Plumbing Compatibility Why Plumbing Needs Attention in a Tub-to-Shower Conversion Ignoring existing plumbing layouts can create drainage problems and raise long-term maintenance risks. When converting a bathtub to a shower , it’s not just about surface upgrades. Drainage systems designed for tubs may not support the flow requirements of showers. Showers need faster, more consistent drainage, which calls for proper pipe sizing and slope. According to most plumbing codes, bathtubs typically use 1½-inch drains, while showers generally require 2-inch drains, though specific requirements vary by local jurisdiction and should be verified with Dover's building department. This means a tub-to-shower conversion usually involves upgrading the drain size. Making this change helps the system meet the current code, reduces the chance of clogs, and supports better long-term performance. Another common issue is the slope. Shower drains need a steady pitch, typically ¼ inch per foot, to keep water moving efficiently and prevent pooling. If the slope isn’t right, pooling can occur, which increases the risk of leaks and mold behind the walls or under the floor. At Cloud 9 Tubs, we start every tub-to-shower conversion by evaluating the existing plumbing. That includes checking pipe condition, layout, and access. This step helps us prevent delays later and ensures the new shower performs reliably. Skipping this kind of planning is one of the most common and expensive mistakes. The Cost of Plumbing Changes Plumbing changes can increase costs when joists, foundations, or wall layouts interfere with access. Homes with slab foundations often require breaking concrete to move pipes. This adds both time and expense. In homes with joist-supported floors, access may be easier, but joist direction and spacing can limit how far a drain can shift. Wall-mounted shower valves also need proper alignment. In tight spaces, adjusting water lines within the wall may require opening multiple sections of drywall. Every added change increases labor and material costs. At Cloud 9 Tubs, we assess structural elements before beginning a bathtub-to-shower conversion. This reduces delays and keeps projects on budget. Mistake #2 – Selecting the Wrong Shower Base Size and Fit Problems Fit and alignment issues can occur because not all tub footprints match the measurements of typical shower pans. Bathtubs are usually 60 inches long, but their depth and width vary. Many prefabricated shower pans come in set dimensions that don’t always match the exact shape or space of a removed tub. This mismatch can create gaps, force awkward wall cuts, or leave uneven flooring exposed. It can also interfere with drain placement or limit door style options. When working with smaller or irregular bathroom layouts, it's important to choose a base that fits within the space without forcing major changes to plumbing or framing. A custom pan or site-built solution may be the better choice in tight quarters. Base Material Considerations The type of shower base you choose affects installation, care, and long-term performance. At Cloud 9 Tubs, we use acrylic bases for most tub-to-shower conversions because they’re durable and easy to maintain. Acrylic is non-porous, so it resists mold growth and keeps cleaning simple. The material is also lightweight and pre-formed, making installation faster and more consistent. When properly supported, acrylic provides a solid feel underfoot. We take extra care during installation to prevent any flexing or movement that could lead to stress over time. Given New Hampshire’s humidity and seasonal shifts, acrylic is a material that offers reliable performance with less upkeep.

Walk-in bathtubs and standard tubs each serve different household needs. Choosing between them depends on mobility, space, and usage habits. A walk-in tub offers a safer bathing experience for people with limited mobility, while a standard tub may suit those with more flexibility. At Cloud 9 Tubs LLC , we help homeowners in Dover, NH, choose the right tub for their space and lifestyle, backed by expert bathtub installation services. The key differences between the standard and walk-in options are discussed in this article, with an emphasis on how each works in a real house. Whether you're renovating for accessibility or updating an older bathroom, knowing the practical pros and cons of each type can help you choose confidently. How the Right Bathtub Supports Everyday Living The right bathtub improves daily routines by supporting comfort, safety, and ease of use. The bathroom is more than a functional space. It plays a role in personal health and daily care. For people with limited mobility or chronic conditions, choosing the correct tub can reduce injury risk and make independent bathing possible. Why Tub Selection Impacts Safety, Comfort, and Independence A poor bathtub fit can lead to slips, strain, or lack of access. According to the CDC, over 230,000 bathroom injuries occur in the U.S. each year, with most involving tubs or showers. For anyone with mobility limitations, a walk-in tub offers safer entry, built-in seating, and support rails. By contrast, standard tubs require more effort to step over and can pose challenges for balance or recovery after surgery. Comfort also depends on how long and how often the tub is used. Soaking tubs with ergonomic contours may suit some, while others may prefer quick, accessible designs that prioritize entry and exit. Walk-in models allow seated bathing, which lowers fatigue during use. Factors That Matter Most to Homeowners in Dover, NH Local homeowners prioritize space, safety, heating efficiency, and ease of use. Older bathroom layouts in many homes can be narrow. Compact walk-in bathtubs can be retrofitted without removing walls while still offering the benefits of hydrotherapy and easy access. Dover residents often consider winter usage, too. Heated surfaces or rapid-fill systems are helpful features in colder climates. Energy efficiency is another common concern, especially with rising utility costs. Choosing the right bathtub means evaluating both fit and operating costs. Matching Product Choice with Individual Routines and Health Needs Tub choice should reflect how each person uses the bathroom, not just how it looks. For someone who bathes daily for muscle relief, a walk-in tub with water jets and a hand-held shower may make sense. For families with small children, a wider standard tub might offer more room for bathing multiple children.
