From Tub to Shower: What to Expect

Turning a tub into a shower is a popular method to modernize a bathroom, save space, and raise property value.

Whether you plan to develop a sleek walk‑in shower, include a luxurious steam feature, or replace an old tub, the process can be easily manageable if you know what to expect.

Below is a guide that walks you through the entire conversion, from initial assessment to final touches.

Why Consider a Bathtub to Shower Conversion?

A bathtub often takes up too much space and feels old‑fashioned in a modern bathroom.

A shower, on the other hand, offers a clean, minimalist look and typically requires less maintenance.

Changing a tub to a shower can also:

Free up floor space for other fixtures or storage

Enhance access for those with mobility challenges

Increase the perceived size of the room

Provide flexible water temperature settings for brief rinses or soothing showers

Essential Things to Think About Before You Start

Assess the Existing Layout

Look at the current plumbing lines, electrical outlets, and the wall structure.

A tub positioned in a corner could need a distinct design compared to one against a wall.

The positioning of the tub drain and showerhead wiring will decide how much re‑wiring or plumbing adjustment is needed.

Verify Building Codes and Permits

Most local building codes require a permit for any plumbing modification.

Even a DIY project requires you to confirm the new shower satisfies safety standards—proper slope, venting, and waterproofing.

Not getting the required permits can result in hefty fines and issues when selling the house.

Determine Your Budget

Entry‑level conversions might cost $1,500–$2,500, whereas top‑tier walk‑in showers with custom glass, rainfall heads, and heated floors can surpass $10,000.

Planning early narrows your options and prevents surprises.

Choose a Shower Style

Options range from a basic step‑in tub‑shower combo to a fully frameless walk‑in shower.

Decide if you desire a single or dual showerhead, a built‑in bench, a steam option, or a rain shower.

Your chosen style will affect the extent of demolition and the materials required.

The Conversion Process in Detail

Step One: Demolition

The first visible change is removing the tub.

If the tub is a cast‑iron or acrylic model, you’ll need a demolition crew or a strong pry bar and sledgehammer to take it down.

The drain pipe will be disconnected, and nearby wall material might require repair or re‑tiling.

Step 2: Plumbing Adjustments

After the tub is removed, the current plumbing can be reused for a shower.

The drain will be redirected to a new shower base or a pre‑finished shower pan.

Based on the layout, a new shower valve might be needed or the existing one modified for a different showerhead.

Usually, a professional plumber is needed to guarantee proper flow rates and pressure.

Step 3: Waterproofing

Waterproofing is a vital component of any shower conversion.

The shower area must be sealed with a waterproof membrane or backer board to prevent leaks.

It entails applying a waterproofing compound, installing a waterproof membrane, and taping the seams.

Correct waterproofing shields walls, floors, and HVAC from moisture damage.

Step 4: Framing and Structure

When installing a walk‑in shower, framing a new enclosure might be necessary.

With a frameless glass wall, any jambs must be reinforced.

The wall may require new studs or additional bracing to support the glass panels and the showerhead fixture.

Step 5: Tiling or Shower Panel Installation

After waterproofing, tile can be laid or a pre‑finished shower panel installed.

Tile work requires effort but offers limitless design opportunities.

Pre‑finished panels simplify installation yet may restrict customization.

Ensure a small gap at the wall bottoms for a proper grout line.

Step 6 – Installing Fixtures

Components include a showerhead, faucet, towel bars, and niche shelving.

Adding a steam feature requires a separate steam unit and 名古屋市東区 リフォーム相談 venting system.

Every fixture must be installed per manufacturer instructions and local codes.

Step Seven: Finishing Touches

Add trim, a shower door or curtain, and install any additional accessories like a heated floor or a rain showerhead.

The last step is cleaning the area and testing the shower for leaks and proper drainage.

Typical Problems and Solutions

Water Leaks – The biggest issue after conversion. Apply waterproofing correctly and double‑check seams before tiling.

Insufficient Drainage – A shower pan with a proper slope (typically 1.

Electrical Hazards – Wiring for a showerhead or lighting should be done by a licensed electrician. Improper wiring may cause short circuits or fire hazards.

Building Code Violations – Make sure your conversion complies with local regulations. Inspector approval can prevent costly re‑work.

Time & Cost Outlook

Timeframe – A typical conversion takes 3 to 10 days, depending on complexity. Simple step‑in conversions finish in a week, whereas walk‑in showers with custom glass and steam may take up to two weeks or longer.

Cost Breakdown –

Tub Removal & Demolition: $200–$400

Plumbing & Permits: $300 to $1,200

Waterproofing & Framing: $400–$1,000

Tile or Shower Panels: $1,000–$4,000

Fixtures & Accessories: $500 to $2,000

Labor (if hiring professionals): $2,000 to $6,000

Total: $5,000–$10,000 (average)

DIY vs. Hiring Professionals

Although a budget‑conscious homeowner may want to DIY, plumbing and waterproofing typically require skilled labor.

A qualified contractor usually ensures code compliance, quicker completion, and fewer surprises.

Nevertheless, if you know plumbing or tiling, a DIY approach can save money—just be willing to invest time in research and learning.
