🛁 Top Picks for Bathroom Caulking
🔝 Best Overall & Waterproof
-
Selleys Wet Area Silicone – Excellent choice for baths and showers with high humidity. Silicone is fully waterproof and flexible — ideal where constant moisture is present. Silicone caulk like this is typically mold- and mildew-resistant and stays flexible over time.
-
Joobond Silicone Sealant – Another premium silicone sealant with great adhesion and durability, perfect for sealing tub-to-wall and tile joints without cracking.
🧼 Great Mold-Resistant & Budget Options
-
Selleys No Mould Silicone Sealant Tube – A solid, budget-friendly silicone caulk that resists mold and mildew — good for regular maintenance caulking.
-
SASHCO CleanSeal Kitchen & Bath Caulk – Kitchen/bath caulk with enzyme tech aimed at reducing mildew. Easy to apply and cleans up with water, though it has more mixed reviews.
💡 DIY & Utility Choices
-
Siroflex Contractor Caulk – A basic caulk for simple sealing jobs; works okay around tubs but may not be as durable or moisture-resistant as silicone.
-
Magic Tub & Wall Peel & Caulk Strip – A peel-and-stick alternative to caulk. Easier to install but less effective long-term than real sealants.
🧠 What to Look for in Bath Caulk
Type matters:
-
100% Silicone – Best for constant water exposure (showers, tubs) because it’s fully waterproof and flexible with strong mold resistance.
-
Siliconized Acrylic – Easier to apply and paintable, but not as durable or moisture-proof as pure silicone — okay for trims or areas that aren’t constantly wet.
-
Latex/Utility Options – Budget or general use, but will usually last less time in wet conditions.
Application tips:
-
Remove old caulk thoroughly.
-
Ensure surfaces are clean and dry before applying.
-
Tool the bead (smooth it with a finger or tool) soon after application for a professional finish.
