Which Toilet Installation Is Better? A Complete Guide to Dry and Wet Mounting Methods

 

🧻 Toilet Installation: Dry or Wet? Here's What You Need to Know (Without the Jargon)

So you're replacing your toilet (or thinking about it) and suddenly your plumber asks:
“Do you want it installed the dry way or wet way?”

Wait... what now? Don’t worry, it’s not about how often you flush — it's all about how your toilet is fixed to the floor. And yes, it does matter!

Here’s the simple breakdown 👇

🚽 What’s a Dry Toilet Installation?

A dry installation uses screws and silicone to attach the toilet to the floor. No messy cement. No drying time. Super clean look.

It works like this:

1. Drill a few holes in the tile

2. Line up the toilet with the drain

3. Screw it down and seal the edges with silicone

Best for:

• Bathrooms with dry/wet separation

• One-piece toilets (they're usually heavier and more stable)

• People who like a clean, minimal finish

Pros:
✅ Quick and easy
✅ Toilet can be removed or relocated later
✅ Neater appearance
✅ Less risk of damage to tiles if done right

Cons:
❌ Not great if your floor isn’t level
❌ May wobble over time if not perfectly aligned
❌ Needs drilling (watch out for hidden pipes or waterproofing!)

🧱 What’s a Wet Toilet Installation?

This is the classic method. The base of the toilet is set into cement mortar. It’s solid, heavy-duty, and not going anywhere anytime soon.

It works like this:

1. Spread mortar on the floor

2. Carefully place and level the toilet

3. Let it set for 1–2 days before use

Best for:

• Older homes with uneven floors

• Bathrooms without dry/wet separation

• People who want a “set it and forget it” solution

Pros:
✅ Super stable and durable
✅ No need to drill holes
✅ Can help seal in odors and leaks

Cons:
❌ Not removable without smashing it (yikes)
❌ Needs a day or two to dry
❌ Can trap smells if ventilation is poor

• Always hire a licensed plumber — a wobbly toilet is no joke.

• Don’t cheap out on silicone or cement. A good seal = no leaks or smells.
