We will walk you through how to reglaze a bathtub yourself, weigh the pros against the cons, and help you decide if you should grab a kit or call a pro.
Key Takeaways
- Reglazing revitalizes an old bathtub for a fraction of the cost of replacing it.
- You can use DIY kits, but the process demands patience, ventilation, and strict safety adherence.
- Success relies on meticulous preparation, including deep cleaning, sanding, and removing old caulk.
- A DIY finish typically lasts 2 to 3 years, while professional refinishing can hold up for a decade.
Can I Reglaze My Bathtub Myself?
You can absolutely take the DIY route, but it requires realistic expectations. Refinishing a tub is not as simple as painting a wall. Kits like the Ekopel DIY Tub and Sink refinishing kit make the materials accessible, but the technique takes focus.
Refinishing saves you hundreds of dollars on labor. However, it requires moderate DIY skills, a steady hand, and the ability to work with strong chemicals.
If you are short on time or patience, hiring a professional ensures a smoother, longer-lasting finish. If you love a project and want to save cash, grab your gear and get started.
Reglazing a Bathtub Pros and Cons
Refinishing is a popular choice for quick bathroom updates, but you should know the trade-offs. Here is a breakdown of the benefits and drawbacks:
Pros
- It costs significantly less than a full replacement.
- You control the schedule and timeline.
- The visual results are immediate.
- It extends the usable life of your current tub.
- You keep old tubs out of the landfill.
- You avoid demolition dust and plumbing hassles.
Cons
- Applying a smooth coat takes practice and skill.
- The prep work is labor-intensive and critical.
- Results are poor on cheap or flexible plastic tubs.
- Fumes can be overpowering, often requiring you to leave the house.
- You can generally only reglaze a tub once or twice.
- The finish is not as durable as a factory-new porcelain surface.
How to Reglaze a Bathtub
Gathering the right supplies is half the battle. Because the chemicals involved are potent, personal protection is non-negotiable.
Safety First
Protect yourself from fumes and contact burns with these items:
- Heavy-duty rubber gloves.
- Safety goggles.
- Rated respirator mask (not just a dust mask).
What You’ll Need
Stock up on these tools before you crack open the epoxy:
- Putty knife.
- Screwdriver set.
- Abrasive scrubbing pad.
- Bucket and large sponge.
- High-quality paint roller and tray.
- Foam paintbrush.
- Plastic drop cloths.
- Caulk gun and waterproof silicone caulk.
- Chemical caulk remover.
- Household bleach.
- Abrasive cleaning powder (like Comet).
- Painter’s tape (Frogtape recommended).
- Wet and dry sandpaper (400 and 600-grit).
- Paper towels.
- Tack cloth.
1. Remove Tub Hardware
You need a blank canvas. Unscrew the overflow plate, remove the drain cover, and take off the faucet spout if possible. Use your putty knife to scrape away every bit of old caulk. If you leave silicone residue behind, the new finish will fisheye and peel.
Top Tip
Hardened sealant is stubborn. Apply a specialized remover like Crown Tuff to soften old caulk before scraping.
2. Clean the Bathtub
Scrub the surface until it is spotless. Deep clean the tub with bleach and water to kill mold. For hard water deposits or rust, use Lime-A-Way Calcium and Rust cleaner. Clorox works well for general disinfecting.
Safety Note
Wear your gloves and goggles during this step. Bleach and rust removers can cause severe skin and eye irritation.
Use an abrasive pad and scour the surface. Don’t worry about scratches; you want to remove all oils and soap scum. Rinse thoroughly and let it air dry.
3. Lay the Drop Cloths
Epoxy is incredibly difficult to remove from tile and grout. Tape plastic drop cloths to the floor around the base of the tub. Mask off the walls and tiles where they meet the tub rim. Frogtape provides a tight seal and prevents paint bleed.
4. Work in a Ventilated Environment
Refinishing products produce toxic organic vapors. Open every window in the bathroom and adjoining rooms. Turn on the exhaust fan and set up a box fan to blow air outdoors.
Put on your respirator now. A standard dust mask is insufficient; use something like the 3M Respirator to block organic vapors and sanding dust.
5. Etch the Surface
Most kits include an etching powder. Apply this with water and an abrasive pad to dull the glossy finish of the old porcelain or fiberglass. Scrub vigorously. This step creates a microscopic texture that helps the new coating bond permanently. Rinse away the residue completely.
6. Time to Sand
Mechanical bonding is key. Sand the wet surface with 400-grit wet/dry paper, focusing on curves and the drain area. Follow up with 600-grit paper. This roughness ensures the epoxy sticks rather than peels.
Wipe the tub down with paper towels until bone dry. Finally, run a tack cloth over the entire surface to pick up any stray dust or lint particles.
7. Time to Prime
Check your kit instructions to see if a separate primer is required. If so, roll it on now using a high-density foam roller. Use a foam brush to get into corners and around the drain hole.
Allow the primer to dry for the time specified on the can.
Pro Tip
Remove loose lint from your roller cover by wrapping it in painter’s tape and peeling it off before you start painting.
8. Mix the Epoxy
Pour the hardener into the epoxy resin (part A and part B) in your paint tray. Stir thoroughly according to the manufacturer’s directions. Move quickly once mixed, as the product has a limited “pot life” before it begins to harden and become unworkable.
Only mix the amount you need for the current coat.
9. Apply the Epoxy Resin
Roll the epoxy onto the tub in smooth, overlapping sections. Alternate between vertical and horizontal strokes to level out the finish and minimize roller marks. Use your foam brush to feather the edges and corners.
Watch for drips and smooth them out immediately. If your kit requires a second coat, adhere strictly to the recoat window (often sticky to the touch but not wet).
Let the tub cure for at least 48 hours. Keep the bathroom door closed and the fan running to vent odors and prevent dust from landing on the wet finish.
10. Caulk and Replace Hardware
Once the finish is fully cured and hard, reattach your overflow plate, drain cover, and spout. Apply a fresh bead of silicone caulk between the tub and the tile/floor.
Pro Tip
Fill the tub with water before caulking. The weight opens the gap slightly when you recaulk it, ensuring the seal doesn’t crack when you take your first bath.
How Long Does Bathtub Reglazing Last?
A DIY reglaze is a temporary fix, typically lasting two to three years before it begins to dull or peel. Professional refinishing uses stronger chemicals and spray equipment, which can extend the lifespan to 10 or even 15 years with proper maintenance. To make it last, avoid abrasive scrubbers and harsh chemicals like bleach.
Average Cost of Refinishing a Bathtub
Hiring a pro is more expensive than a DIY kit but cheaper than replacement. Professional refinishing generally costs between $285 and $950. The price varies based on your location, the condition of the tub, and whether it requires extensive repairs for chips or rust.
Refinishing Vs. Replacing a Bathtub
This decision comes down to budget and the condition of the tub “bones.” If you have a high-quality cast iron tub that is simply ugly, reglazing is the best option. It restores the look without the heavy lifting.
However, if the tub has structural cracks, major rust, or you hate the size, replacement is the better long-term investment. While a new tub might only cost $200, the labor, plumbing, and tiling required to install it can easily push the total cost over $3,000.
FAQs
What Is the Difference Between Reglazing and Refinishing a Bathtub?
These terms are used interchangeably today. Technically, reglazing implies creating a new glass-like surface, while refinishing refers to the process of sanding and painting with epoxy. For the average homeowner, they mean the same thing: restoring an old tub with a new coating.
Can You Reglaze a Bathtub Twice?
Yes, you can reglaze a tub multiple times, but the results diminish. The previous coating must be completely stripped or sanded down aggressively for the new coat to bond, which adds significant labor to the project.
How Long Does It Take to Reglaze a Bathtub?
The actual labor takes about two to four hours. However, the preparation, drying time between coats, and final cure time means the bathtub will be out of commission for at least 2 to 3 days.
How Long Does a Reglazed Tub Take to Dry?
Most epoxy kits require 24 to 48 hours to cure completely. Do not use the shower or bath during this window, as water will ruin the finish and trap moisture underneath the coating.
How Should I Clean a Reglazed Bathtub?
Use non-abrasive, liquid cleaners to protect the new finish. Avoid bleach, steel wool, or scouring pads, as these will scratch the epoxy and cause it to peel prematurely.
All Praise the Bathtub Reglaze
The transformation after a reglaze is dramatic. Your bathroom brightens up, and the tub looks factory-fresh. It buys you years of use without the headache of a demolition.
Mastering how to resurface a bathtub is a valuable skill that saves money and reduces waste. If you have the patience for the prep work, you can achieve professional-looking results. Grab your respirator and get to work!
