Practical Tips for Converting Your Tub to a Walk-In Shower in Montgomery

Tips And TricksUpdated July 20, 2026

Swapping out an old tub for a walk-in shower is one of the most common bathroom upgrades we handle in Montgomery. Many local homes, especially those built in the subdivisions of the late 20th and early 21st centuries, have standard alcove tubs that see less use as families' needs change. Converting that space to a walk-in shower provides better safety, easier access, and a more open feel. But this project calls for careful planning and knowledge of the plumbing behind your walls.

Why Walk-In Showers Suit Montgomery Homes

Our region features a mix of housing, from newer construction to older homes closer to downtown. Most have reliable water pressure and modern PVC drain lines, though homes from earlier decades may still have some outdated plumbing materials. A walk-in shower works well in almost any layout, especially for households wanting safer, low-threshold entry instead of climbing over a tub wall. This change also appeals to multigenerational families or those planning for aging in place, since slip-and-fall risk drops with a well-designed shower and sturdy grab bars.

What to Check Before Removing the Tub

  • Drain Location and Size: Most bathtubs have a 1.5-inch drain. Current code calls for a 2-inch drain for showers, so you may need to upgrade and rework the trap.
  • Water Supply Lines: Check for corrosion, leaks, or outdated materials. Galvanized or polybutylene pipes should be updated. Our pipe repair and repiping team can handle these upgrades if needed.
  • Waterproofing and Subfloor: The shower base needs solid, level support. Look for old water damage or rot around the tub walls. Correcting this now prevents future headaches.
  • Existing Venting: The new shower must tie into a properly vented drain. We check vent stacks and look out for siphoning issues during the remodel.

Plumbing Upgrades that Make a Difference

Even in homes with fairly recent plumbing, minor upgrades go a long way for comfort and reliability. A pressure-balanced valve prevents sudden temperature swings if someone flushes a toilet or runs the washing machine. Upgrading the showerhead, valves, and trim gives the space a modern feel and can help with water savings. If you've noticed hot water issues or an aging tank, pairing a tub-to-shower conversion with water heater services is smart, especially since the harsh winters around here are tough on older heaters.

Drainage and Waterproofing Essentials

Proper drainage keeps the new shower running smoothly. We always slope the shower base toward the drain (at least 1/4 inch per foot) to avoid standing water. For tiled showers, a robust waterproofing layer is a must. We use either a PVC pan liner or a liquid-applied membrane, with corners and seams sealed tight. For fiberglass or acrylic pans, careful caulking and snug drain connections prevent leaks down the road. If you notice slow drains elsewhere or have older clay-tile sewer lines, a professional drain cleaning can keep everything flowing.

Smart Fixture and Accessory Choices

Swapping out fixtures during a remodel is the best time to add comfort and utility. Consider a handheld showerhead or a grab bar anchored into wall studs. We usually recommend a single-lever faucet for easy control. Upgrading or relocating the exhaust fan helps clear out the humidity from steamy showers, protecting your home against mold and paint failure. If you're including new sinks or changing faucets, our faucet and fixture installation crew can ensure everything is watertight and up to spec.

A Few Common Issues to Watch For

  • Unlevel floors or out-of-square walls can make shower base installation tricky. Sometimes minor carpentry is needed first.
  • Low water pressure or fluctuating temperatures may point to corroded supply lines or a faulty PRV (Pressure Reducing Valve).
  • Hidden water leaks from old tub surrounds or behind walls, use a proven leak detection and repair process before closing up the new shower.
  • Unexpected drain height or distance from the main stack, which can require extra pipe work or floor cuts.

Every home is a little different, especially in communities with both new and old housing. Careful prep, experienced plumbing, and the right fixture choices ensure your new walk-in shower will serve you well for years.

Frequently Asked Questions

Most bathtub drains are 1.5 inches, but showers usually require a 2-inch drain for better flow and code compliance. In many Montgomery homes, we need to update the drain and possibly the trap when converting to a walk-in shower.

If your supply lines are copper, PEX, or newer PVC and in good shape, they can usually stay. But if you have galvanized, polybutylene, or visible corrosion, repiping is wise for reliable pressure and fewer leaks.

Proper waterproofing is crucial. We apply a waterproof membrane under tile or use molded pans, always sealing corners and connections thoroughly. Checking for hidden leaks before finishing walls helps protect your investment.

The timeline depends on your home's condition and any piping upgrades. Most jobs in local homes take a few days, but extra time could be needed for repairs or custom tile work.
