How to Tile Around a Toilet
A step-by-step guide to tiling your bathroom floor around the toilet area — covering toilet removal, flange height, curved cuts, sealing, and resetting the toilet for a clean, professional result.
Quick Answer
Always remove the toilet before tiling. Tile the entire floor underneath, ensure the flange sits flush to 1/4" above the finished tile, then reset the toilet with a new wax ring or rubber seal and caulk the base with silicone.

1Why should you always remove the toilet first?
The single most important rule when tiling a bathroom floor: remove the toilet before you start. This is not optional. While it may seem tempting to tile around the toilet to save time, doing so creates problems that far outweigh the 15 minutes it takes to pull the fixture.
Tiling Around (Not Recommended)
Leaves gaps, looks unprofessional
Tiling around a toilet leaves visible gaps between the tile and the toilet base. These gaps collect moisture, bacteria, and grime. If you ever need to replace the toilet with a different model, the footprint may not match, exposing bare subfloor.
Remove, Tile, Reset (Recommended)
Clean finish, flexible for future changes
Removing the toilet gives you a complete, continuous tile floor. You get cleaner cuts around the flange, proper waterproofing under the full footprint, and the freedom to change toilets in the future without retiling.
How to Remove a Toilet (Quick Steps)
- Turn off the water supply valve behind the toilet and flush to empty the tank and bowl. Sponge out remaining water.
- Disconnect the water supply line from the fill valve at the bottom of the tank.
- Pop off the bolt caps at the base and remove the nuts from the closet bolts (use penetrating oil if rusted).
- Rock the toilet gently to break the wax seal, then lift straight up and set it on a drop cloth or cardboard.
- Stuff a rag into the open flange to block sewer gas while you work. Scrape off the old wax ring from the flange.
Tip: Two-Person Lift
A standard toilet weighs 60-80 lbs. While one person can manage it, having a helper makes the lift safer and reduces the risk of cracking the porcelain or damaging your new tile later during reset.
2How do you get the toilet flange height right?
The toilet flange (also called a closet flange) is the pipe fitting that connects the toilet to the drain pipe in the floor. After tiling, the relationship between the flange and the finished floor surface is critical. Get this wrong and you will have a leaking toilet.
Ideal Height
Flush to 1/4" above finished tile
The flange should sit on top of the finished tile, flush with the surface or up to 1/4 inch above it. This ensures the wax ring compresses properly against the bottom of the toilet and creates a reliable seal.
Flange Too Low
Below tile surface after installation
If the new tile raises the floor and the flange now sits below the surface, the wax ring cannot compress properly. This is the number one cause of toilet leaks after a bathroom retile. Fix with a flange extender or spacer ring before resetting the toilet.
Flange Too High
More than 1/4" above finished tile
A flange that protrudes too far above the tile will prevent the toilet base from sitting flat. The toilet will rock, which eventually breaks the wax seal. If the flange is more than 1/4 inch above the tile, use an extra-thick wax ring or shim the toilet base.
Calculating Flange Height Before You Tile
Before starting, measure the current flange height relative to the subfloor. Then add your tile thickness plus the thinset mortar bed (typically 3/16" to 1/4"). If the math shows the flange will end up below the finished surface, plan to install a flange extender after tiling.
| Tile Thickness | + Thinset | Total Floor Rise | Flange Fix Needed? |
|---|---|---|---|
| 1/4" (6mm) | 3/16" | ~7/16" | Usually yes |
| 3/8" (10mm) | 3/16" | ~9/16" | Yes, extender needed |
| 1/2" (12mm) | 1/4" | ~3/4" | Yes, extender needed |
3How do you cut tile to fit around the flange?
The flange opening is roughly 4 inches in diameter, and the surrounding tiles will need curved cuts to fit neatly around it. This is the trickiest part of the job, but with the right technique it is straightforward.
Make a Template First
Before cutting any tile, create a template from cardboard or heavy paper. Lay the template material over the flange area and trace the curve. Cut the template and test-fit it. When it fits perfectly, transfer the shape to your tile with a marker.
Cutting Methods
Angle Grinder + Diamond Blade
Best for curved cuts in porcelain and ceramic
A 4.5-inch angle grinder with a continuous-rim diamond blade is the best tool for cutting curves in tile. Score the line first, then make multiple shallow passes. Work slowly and let the blade do the cutting — do not force it.
Tile Nippers
Good for fine-tuning and small adjustments
After making the main curve with a grinder, use tile nippers to nibble away small amounts for a precise fit. Take tiny bites — removing too much at once can crack the tile.
Wet Saw with Plunge Cuts
For the straight portions of the cut
A wet saw handles straight cuts well but cannot follow curves. Use it to make relief cuts (a series of parallel straight cuts up to the curve line), then snap off the fingers and smooth with a rubbing stone.
Gap Size
Leave a 1/4-inch gap between the tile edge and the flange. This gap will be hidden under the toilet base and allows for expansion. Do not try to get a skin-tight fit — it is unnecessary and risks cracking the tile.
4How do you tile the bathroom floor around a toilet?
With the toilet removed and the flange prepared, you can now tile the entire bathroom floor as a continuous surface. This is far easier than trying to work around the toilet base.
Layout and Dry Fit
Start by dry-fitting your tile layout from the most visible wall (usually the doorway) toward the toilet area. The flange area is typically the least visible part of the floor, so plan your layout so that cut tiles end up near the toilet and full tiles are at the entrance.
Installation Order
- Spread thinset mortar with a 1/4" x 3/8" notched trowel, working in small sections (about 3-4 sq ft at a time).
- Set full tiles first, working from the doorway toward the toilet area. Use spacers for consistent grout lines.
- When you reach the flange area, set your pre-cut curved tiles around the opening. Do not tile over the flange itself.
- Back-butter the curved tiles with thinset for full adhesion since they are irregular shapes.
- Allow the thinset to cure for 24 hours before grouting. Allow grout to cure for another 24 hours before resetting the toilet.
Tip: Protect the Flange
Tape over the rag in the flange opening before tiling to prevent thinset or grout from falling into the drain pipe. Also keep thinset off the top surface of the flange — the wax ring needs a clean, flat surface to seal against.

5Should you use a wax ring or a rubber gasket seal?
Every time you reset a toilet, you need a new seal between the toilet and the flange. The traditional option is a wax ring, but modern rubber gasket seals have become popular. Here is how they compare:
Traditional Wax Ring
$3-5, single use, proven reliable
Wax rings have been the standard for decades and work well when installed correctly. However, they are single-use — once compressed, they cannot be repositioned. If you set the toilet down crooked or need to adjust, you must start over with a new ring. Use an "extra-thick" wax ring if the flange sits slightly below the tile surface.
Rubber Gasket Seal
$10-15, repositionable, flexible fit
Brands like Korky, Fluidmaster "Better Than Wax," and Oatey make rubber or foam gaskets that create a compression seal. The big advantage: you can lift and reposition the toilet without replacing the seal. They also accommodate flange height variations better than wax, which makes them ideal after a retile when the floor height has changed.
When to Use Extra-Thick or Stacked Rings
If the flange sits more than 1/4" below the finished tile and you cannot install a flange extender, you can use an extra-thick wax ring or stack two standard wax rings. However, a flange extender is always the better solution — stacked rings increase the chance of a failed seal over time.
6How do you reset the toilet on new tile?
After your tile and grout have fully cured (at least 48 hours total), it is time to reset the toilet. Take your time here — a rushed reset leads to leaks and a rocking toilet.
Step-by-Step Reset
- Install new closet bolts into the flange slots. Make sure they are centered and upright. Some flanges have a slot that holds the bolt head — slide them in and quarter-turn to lock.
- Install the flange extender if needed. Dry-fit it first, then secure with stainless steel screws into the subfloor (not into the tile).
- Place the wax ring or rubber gasket onto the flange (wax rings go wax-side up on the flange; rubber gaskets typically press onto the toilet outlet first — follow the manufacturer's instructions).
- Remove the rag from the drain pipe. This is the most commonly forgotten step.
- Lower the toilet straight down onto the closet bolts. Align the bolt holes in the toilet base with the bolts and press down firmly with a slight rocking motion to set the seal. Do not lift and reposition if using a wax ring.
- Hand-tighten the nuts onto the closet bolts, alternating sides (left, right, left, right). Then snug with a wrench — do not overtighten or you will crack the porcelain base.
- Reconnect the water supply, turn on the valve, and let the tank fill. Flush several times and check around the base for any signs of leaking.
Critical: Do Not Overtighten
Cracking the toilet base by overtightening the closet bolt nuts is one of the most common DIY mistakes. Tighten until the toilet is snug and does not rock — then stop. If the toilet rocks, use plastic shims at the base rather than cranking down harder on the bolts.
7Should you caulk or grout at the toilet base?
The final step is sealing the gap between the toilet base and the tile floor. This is a surprisingly debated topic, so let us break down the options.
100% Silicone Caulk (Recommended)
Flexible, waterproof, code-compliant
Use 100% silicone caulk matched to your grout color. Silicone stays flexible as the toilet shifts slightly with use, creates a waterproof barrier, and is required by most plumbing codes (IPC 405.5). Apply a continuous, thin bead around the entire base and smooth with a wet finger or caulk tool.
Grout (Not Recommended)
Rigid, cracks easily, hard to remove
Grout is rigid and will crack as the toilet moves. Cracked grout looks messy and allows water to seep underneath. It is also extremely difficult to remove if you ever need to pull the toilet again.
The "Leave the Back Open" Debate
Some plumbers recommend leaving the back of the toilet base (the side facing the wall) uncaulked. The reasoning: if the wax ring fails, water will leak out the back where you can see it, rather than being trapped invisibly under the caulk. This is a valid argument, but most building codes require a full seal. If you are in an area where code requires it, caulk all the way around. If code is flexible, leaving a 2-inch gap at the back is a reasonable compromise.
Caulk Application Tip
Apply painter's tape along the tile and the toilet base before caulking for a perfectly straight line. Apply the caulk, smooth it, then peel the tape immediately while the caulk is still wet. The result is a clean, professional-looking bead every time.
8Pro Tips
- Buy a flange extender kit before you start tiling — it is much easier to have one on hand than to make a hardware store run mid-project
- Use stainless steel closet bolts instead of brass — they will not corrode or snap when you need to remove the toilet years later
- Practice your curved cuts on a scrap tile first before cutting the actual piece — porcelain is expensive
- Take a photo of the toilet area before removal so you can reference the bolt locations and supply line routing during reset
- If you are tiling over an existing floor, factor the added height into your door clearance — you may need to trim the bathroom door
- Order 10-15% extra tile to account for cuts around the toilet area and other fixtures — curved cuts have a higher breakage rate than straight cuts
