Cost to Re-caulk a Bathtub or Shower
Re-caulking a bathtub or shower replaces the seal along the joint to stop water from getting behind the fixture. Homeowners commonly take it on when the existing caulk has cracks, gaps, or mold that can create leak paths. The job is straightforward, but a lasting, neat bead depends on fully removing old caulk and working the new bead smooth in one pass.

DIY or call a pro?
This is a DIY-friendly maintenance job using a caulk gun, caulk-removal tool or utility knife, painter's tape, and a rag. Consider a professional if removing all of the old caulk or laying and tooling a steady bead feels uncomfortable. Ventilate the bathroom while silicone caulk cures, and keep the new seal dry until it has cured fully.
Frequently asked questions
- Can I re-caulk a bathtub or shower myself?
- Yes. It is an easy DIY job, provided the joint can be cleaned completely and allowed to dry before new caulk is applied. A professional is worth considering if the old caulk resists full removal or if creating a smooth, continuous bead is beyond your comfort level.
- What makes bathtub or shower re-caulking cost more?
- The price can rise with the size of the job, labor time, and materials. Small jobs may also carry a minimum or trip charge.
- Should a bathtub be filled before applying new caulk?
- Yes. Fill a tub with water before caulking so the joint is at its widest while the caulk cures. This helps the seal cure in the position it needs to accommodate.
- What should I check before buying caulk for a shower joint?
- Inspect the existing caulk for cracks, gaps, and mold, since these are the leak paths being sealed. Choose a mildew-resistant kitchen-and-bath caulk that is silicone or siliconized latex, and clean the joint with rubbing alcohol so soap scum and moisture are cleared away and adhesion is strong.
