How to Resurface a Shower Pan
Shower floors take the most abuse. Learn how to resurface them properly — and why DIY on floors often fails faster than on walls.
Types of Shower Pans That Can Be Resurfaced
Fiberglass/Acrylic Pans
Most common type. Can be resurfaced with proper prep. Professional refinishing works well on these materials.
Tile Shower Floors
Can be resurfaced if grout is in good condition. Coating fills grout lines. Professional anti-slip additive recommended.
Cracked Pans
Cracks must be repaired first. If pan is cracked through to subfloor, water damage may require replacement instead.
Leaking Pans
If water is leaking to subfloor, resurfacing won't help. The pan and possibly subfloor need replacement.
DIY Shower Pan Resurfacing Steps
Deep Clean with Mold Killer
Shower floors often have mold in grout or textured areas. Use bleach solution first, then TSP. Scrub thoroughly and rinse well.
Repair Cracks
Fill cracks with appropriate filler (fiberglass repair for fiberglass, epoxy for tile). Let cure and sand smooth.
Sand Entire Surface
Use 320-400 grit. Sand the entire floor evenly. This is harder on textured surfaces — be thorough.
Mask Drain & Walls
Tape off drain, caulk lines, and walls. Protect any areas you don't want coated.
Apply Coating with Anti-Slip
Apply 2-3 coats. For safety, add anti-slip additive to final coat or use textured roller. Smooth floors are dangerous when wet.
Cure 72+ Hours
Floors need extra cure time due to foot traffic. Wait minimum 72 hours, ideally 5-7 days before regular use. Recaulk drain.

Shower Pan FAQs
Is resurfaced shower floor slippery?
It can be if anti-slip additive isn't used. Professional refinishing includes textured anti-slip coating. DIY must add anti-slip additive to the final coat or risk creating a dangerous slick surface.
Can you refinish just the shower floor?
Yes. We often refinish just the pan if walls are in good condition. We can also refinish pan + walls together for a complete refresh. Matching the existing wall color to a new floor is possible.
How long until I can use the shower?
Professional refinishing: 48-72 hours minimum, 5-7 days for full cure. DIY: same timeline but critical to follow — floors fail faster if used too soon. Foot traffic stresses uncured coating.
