Swimming with an ostomy can be a refreshing and enjoyable activity, but it sometimes comes with the challenge of preventing skin rash and irritation around the stoma. If you swim regularly and notice a rash on your peristomal skin, it might be due to pool chemicals or moisture trapped under the wafer. Here are some helpful tips to protect your skin and keep your appliance in good condition without using up all your supplies:

1. Moisture management:
- After swimming, use a hair-dryer on a low, cool setting to thoroughly dry the wafer and tape.
- Try short "test soaks" in the bathtub to determine how long your appliance can handle water exposure before issues arise.

2. Extra mechanical support:
- Consider wearing an elastic swim band or wrap along with waterproof tape, such as 3M waterproof tape, to keep your system secure while swimming.

3. Skin protection and waterproof barriers:
- Use a full-cover waterproof ostomy protector to shield your appliance from water.
- Some swimmers have found success with Aqua Seal ostomy covers, which completely seal the wafer and prevent leaks. Note that Aqua Seal may need to be ordered from the U.S. if you're in the U.K.

4. Possible causes to investigate:
- Pool chemicals like chlorine might react with the wafer adhesive, causing irritation. If the rash continues, try different wafer brands or tape materials and consult a stoma nurse for advice.
- Excessive sweating can also weaken adhesion. Using extra tape and protective covers can help if you tend to sweat a lot.
