What’s the Best Grout to Use in a Shower? A Contractor’s Advice

Showers are tough on grout. And it’s not just splashes — it’s the daily humidity, steam, and condensation. All that moisture can break down grout fast if you don’t use the right kind. Here’s what you need to know before choosing grout for your shower remodel.

When homeowners ask about the best grout for shower installation, I give it to them straight: the type of grout you choose determines whether you’ll enjoy a mold-free, low-maintenance shower — or end up regrouting in a year.

💀 The Problem with Cement-Based Grout

Let me be blunt: cement-based grout does not belong in a shower. It’s porous, which means it absorbs water like a sponge. Even when sealed, it eventually breaks down.

Here’s what happens over time:

• Mold and mildew growth
• Cracking, shrinking, and discoloration
• Water intrusion behind tile
• Costly regrouting or repairs

It might be cheaper upfront, but it’s a bad investment. Especially in wet areas like showers or tub surrounds, cement grout simply doesn’t hold up.

✅ Why Epoxy Grout Is the Right Call

When I remodel a bathroom — especially a walk-in shower — I use epoxy grout. Period.

Here’s why epoxy is the best grout for shower projects:

• Waterproof: Epoxy doesn’t absorb water, so it resists mold and bacteria.
• Stain-resistant: No more worrying about hard water spots or soap scum.
• Crack-resistant: It flexes better and holds up over time.
• No sealing required: Unlike cement grout, epoxy is naturally sealed.
• Extremely durable: It’s used in commercial kitchens, pools, and spas.

Yes, it costs more. But if you want peace of mind and a low-maintenance shower for the long haul — epoxy is the smart move.

🛠️ Planning to DIY? Read This First

Epoxy grout is not for beginners. Installation is trickier than cement grout. You have to:

• Mix and apply fast — it starts curing right away
• Wipe excess grout and haze before it hardens
• Use special cleaning tools during application

If you let the epoxy haze dry on the tile? Good luck getting it off without scratching or damaging the finish.
