How Much Does It Cost to Replace a Fiberglass Tub and Surround? The Ultimate Guide

Hey there! If you‘re reading this, you‘re likely considering a bathtub and surround replacement project. I know first-hand how daunting yet exciting this project can be. Replacing these bathroom elements can completely transform the space, but it‘s no small task.

In this comprehensive guide, I‘ll walk you step-by-step through the entire process so you can determine if a full replacement is right for your home and budget. I‘ll share tips from my experience as a home renovation contractor to help you make the best material choices while avoiding potential pitfalls.

Total Cost Breakdown

Let‘s start by talking budgets. For a standard 5-by-3-foot alcove tub with full surround, you can expect to spend:

• Tub – $500 to $1,500+
• Surround – $500 to $2,500+
• Plumbing – $200 to $1,000
• Structural work – $500 to $2,000
• Labor – $1,000 to $3,000
• Other costs – $500 to $1,000

This brings the total cost range to $2,500 to $4,500+ for the full project.

Now let‘s dive into what impacts costs in each area.

Tub Cost Factors

The tub itself comprises about 20-30% of your total budget. Materials make the biggest difference in tub costs:

• Fiberglass tubs – Most affordable at $300 to $700 installed. Scratches easily.

• Acrylic tubs – Range from $500 to $1,500. More durable with a glossy look.

• Porcelain on steel – Around $750 to $1,200. Prone to chipping over time.

• Enameled cast iron – $1,000 to $1,500+ for high durability but very heavy.

You can also choose from many options like jetted tubs, air baths, and custom sizes and shapes that raise costs to $2,500+.

Surround Cost Considerations

The surround typically represents 30-40% of the total replacement cost. Options include:

• Fiberglass surrounds – Most economical at $500 to $1,000 installed.

• Acrylic surrounds – Run $1,000 to $1,500+ for a more durable product.

• Cultured marble – $1,500 to $2,500+ installed. Mimics real marble‘s look.

• Ceramic tile – As low as $1,000 for basic tile to $2,500+ for stone and intricate designs.

Plumbing Costs

Replacing your tub and surround will likely require plumbing modifications to accommodate a new layout. Expect costs around:

• $200 to $500 – Basic drain adjustments and new supply lines
• $500 to $1,000 – Moving drain location and adding jetted tub fixtures

Upgrading faucets, handles, and other fixtures can raise costs above $1,000 quickly.

Potential Structural Costs

Since you‘re replacing the entire tub surround, some structural work is often needed:

• Wall framing – $200 to $500 to replace damaged studs
• Drywall – $300 to $800+ for drywall repair/replacement
• Flooring – $500+ if subfloor needs reinforcement

Labor Adds Up Quickly

With multiple trades involved, professional installation is advised. Labor rates typically range:

• Plumbing – $50 to $80 per hour
• Carpentry – $60 to $90 per hour
• Tiling – $45 to $75 per hour

Even seemingly simple jobs can take 10-20+ hours total.

Miscellaneous Costs

Miscellaneous supplies, fees for disposal, and more can add $500 or more:

• Permits – $50 to $250
• Caulk/lumber/paint – $200
• Disposal fees – $100 to $300
• Contingency funds – 10% of total budget

Step-by-Step Installation Process

Now that you know what to expect cost-wise, let‘s look at the installation process. I‘ll overview the steps while focusing on the critical details.

Preparing the Bathroom

The first step is preparing the space by:

• Removing accessories like shower rods, curtains, soap dishes, etc.
• Laying drop cloths to protect existing floors and walls from damage.
• Clearing a path from the door to the tub area to allow removal of the old tub.

Safety comes first – be sure to turn off the water supply and drain the old tub completely before beginning demolition.

Removing the Old Tub and Surround

With prep complete, it‘s time for teardown:

• Cut away caulk – Use a utility knife to cut the caulk beads sealing the surround panels. This allows you to separate the panels from each other and the walls.

• Detach surround – A reciprocating saw works well to cut through fiberglass or acrylic surrounds while minimizing wall damage. Wear safety goggles and a mask to avoid breathing in fiberglass dust.

• Disconnect plumbing – Removing the old tub requires disconnecting the supply lines, faucet fixtures, and P-trap underneath. A wrench is usually needed to loosen fittings.

• Remove tub – Cast iron or steel tubs often need to be broken up with a sledgehammer for removal. Lighter acrylic or fiberglass tubs can be carried out whole in most cases.

Inspect and Repair Walls and Floors

With the tub gone, you now have full access to inspect and repair the underlying walls and floors:

• Check wall studs – Examine for any moisture damage or deterioration. Replace any compromised studs to ensure structural integrity.

• Inspect floor – The flooring under the tub takes a lot of weight and moisture over the years. Repair or replace subfloor sections as needed to create a level surface.

• Prepare walls – Damaged or moldy drywall around the tub will need to be replaced to create a clean surface for the new surround.

Taking care of these repairs now prevents major headaches down the road!

Install the New Bathtub

Once all repairs are complete, it‘s time to put in the new tub:

• Position tub – Have helpers lift the tub into place. The drain hole should align with the drain pipe coming up from the floor.

• Connect drains – Attach the drain assembly, making sure the rubber gaskets form a tight seal. Secure with drain pipe connectors.

• Seal bottom – Run a bead of adhesive completely around the bottom edges of the tub to prevent moisture from seeping underneath.

• Attach plumbing – Connect the hot and cold supply lines to the faucet fixtures. Also attach any other features like an air jet pump.

• Caulk perimeters – Run a smooth, consistent bead of tub and tile caulk around the edges where the tub meets walls, floor, and rim.

Add the New Surround

The tub provides a strong foundation for your surround installation:

• For fiberglass – Apply adhesive to the walls per the manufacturer instructions. Carefully press the surround panels into place. Use caulk to seal edges and seams.

• For acrylic – After adhering to the walls, attach L-brackets along the vertical seams for better support. Fill gaps with caulk.

• For tile – Mark the wall height to guide your first row. Use spacers between tiles to ensure even spacing.

Take your time with the surround installation to achieve straight, seamless results.

Finishing Touches

You‘re in the home stretch! Finish by:

• Sealing all edges – Do a thorough final pass with tub and tile caulk at all edges and openings. This prevents moisture from penetrating.

• Rehanging fixtures – Once caulk has set, reinstall any shower rods, grab bars, or shelves pulled down initially.

• Painting/decorating – With your gorgeous new tub and surround in place, it‘s time to paint the walls or decorate as desired!

Key Material Considerations

One of the biggest decisions you’ll face is what material to use for the bathtub and surround. Let’s explore some of the top options:

Bathtub Materials

Acrylic

• Most popular material for its durability, glossy appearance, and heat retention.

• More expensive but retains its shiny, like-new look for 15+ years when cared for.

Maintaining Your Investment Over the Long Run

The way you care for your new tub and surround determines how long they last. With proper maintenance you should enjoy your bathroom upgrade for 15-25 years!

Here are my top tips for maximizing longevity:

• Clean gently – Use only non-abrasive cleaners and soft sponges/cloths to avoid scratching surfaces. Avoid harsh chemicals like bleach that can damage materials over time.

• Re-caulk annually – Sealing all edges and seams with a flexible, waterproof caulk prevents moisture from penetrating the surfaces and causing deterioration or mold growth.

• Limit direct water exposure – Using a shower curtain or doors keeps stray water spray contained. This prevents possible water damage to walls and ceilings.

• Address issues immediately – Don‘t ignore small cracks in grout or caulk. Repair right away to avoid worsening damage.

• Consider professional refinishing – Have the tub and surround re-glazed around years 10-15 to refresh their appearance and add years of life.

Is Refinishing Right for You?

Given the high costs of a full replacement project, you may be wondering if refinishing your existing tub and surround is a better option. Let‘s compare the pros and cons:

Benefits of Bathtub Refinishing

• Lower cost – $400 to $1,000 vs. $2,500+ for replacement.

• Faster timeline – Just 1-2 days vs. 2 weeks or more for replacement.

• Less demolition – Existing tub can usually remain vs. full teardown.

Drawbacks of Refinishing

• Shorter lifespan – Lasts 3-5 years vs. 15+ years with new tub and walls.

• Existing damage remains – Doesn‘t fix cracks, leaks, or rotting subsurfaces.

• Limited options – Fewer finishes and color choices than replacement.

Advantages of Full Replacement

• Fresh new look – Entirely new components with latest styles.

• Fixed problems – Replaces any damaged or deteriorated underlying structures.

• Customization – Wider range of colors, finishes, and material upgrades.

• Long-lasting results – A full new tub and walls should last 15-25 years with proper care.

Downsides of Full Replacement

• Higher cost – Significant material and labor expenses of $2,500+ on average.

• Disruption – Entire bathroom unusable for 2 weeks or longer during renovation.

• Complex project – Much more involved demolition and installation work.

So weigh your budget, how long you plan to stay in the home, and the scope of any existing damage to determine if replacement or refinishing is the best value for your situation.
