Installing a new toilet is more than just picking something that looks good. The right toilet means efficient performance, fewer issues down the road, and—when installed properly—years of trouble-free use. Below are everything you should know when selecting a toilet before the installation process.
Why the Right Toilet Matters
A good toilet choice affects:
- Water efficiency (water usage per flush)
- Comfort (seat height, bowl shape)
- Ease of cleaning and maintenance
- Compatibility with your existing plumbing setup
- Long-term cost savings
If you try to install a toilet that doesn’t match your plumbing or space constraints, you could end up paying more to adjust things later.
Key Features to Consider
Here’s what to evaluate before making your decision:
1. Bowl types and shapes
| Type | Description | Best For |
|---|---|---|
| Round bowl | Compact, saves space | Small bathrooms or tight fronts |
| Elongated bowl | More seat space, comfort | Larger bathrooms, frequent usage |
| Wall-hung | Minimal floor contact, modern look | Want to save floor area / easier cleaning |
2. Seat height (“Comfort Height”)
- Standard height: ~15″ from floor to rim
- Comfort/ADA height: ~17-19″ – easier for seniors, those with mobility issues
3. Flushing mechanism
- Gravity feed: standard, reliable for most households
- Pressure-assisted: more powerful flush, good for clogging issues
- Dual flush: option to save water (half flush for liquid waste, full for solids)
4. Water efficiency / Gallons per Flush (GPF)
- Older toilets may use 3.5+ gallons per flush
- Modern low-flow toilets use about 1.28 GPF or less
- Look for WaterSense or similar certifications
5. Rough-in distance
- This is the distance from the wall to the center of the closet bolts/pipes
- Standard rough-in is ~12″ but could be 10″ or 14″ — measure accurately
6. Construction and materials
- Porcelain (china) is the standard — look for quality glazing to resist stains
- One-piece vs. two-piece toilets: one-piece easier to clean; two-piece easier to ship / replace parts
Common Mistakes When Choosing a Toilet
Avoiding these can make installation smoother:
- Failing to measure rough-in distance → new toilet doesn’t fit
- Choosing a bowl shape that clashes with room layout
- Buying a toilet with a flush rate that’s too low for your needs
- Overlooking water supply line location / shut-off valve accessibility
- Ignoring overflow concerns (tank overflow, base sealing)
Installation Preparation Tips
Before the installer shows up (or before DIY), prepare:
- Clear the area around the toilet → remove rugs, accessories
- Turn off water supply and drain the old toilet / tank
- Inspect the flange (needs to be level, damage-free)
- Have proper wax ring / seal ready
- Confirm access to water line and shut-off valve
What to Look for in a Professional Toilet Installation
Having chosen your toilet, installation is next. A good installer (or plumbing service) should:
- Inspect your plumbing and flange before installation
- Use proper seals (wax ring or modern seal) to prevent leaks
- Level the toilet so it doesn’t rock or wobble
- Tighten bolts properly (not too much — avoid cracking)
- Connect water supply properly, test for leaks
- Leave the area clean and ensure everything flushes correctly

Questions to Ask Before You Buy
- What is the rough-in measurement, and does your new toilet match it?
- How many gallons per flush (GPF)? Will it save you water/costs over time?
- How tall is the seat? Comfortable for everyone in the house?
- What is the warranty on the flushing mechanism / parts?
- What extra labor might be needed (e.g. replacing damaged flange, adjusting floor)
