Moving a toilet can range from a relatively simple DIY project to a complex and potentially expensive undertaking, primarily depending on the distance you're moving it and the existing plumbing. The literal act of installing the toilet isn't the difficult part; it's dealing with the drain and water supply lines.
Here's a breakdown of the factors influencing the difficulty:
Key Considerations:
-
Distance of the Move: A move within a few inches, perhaps to accommodate a slightly larger vanity, is far easier than relocating the toilet to an entirely different part of the bathroom.
-
Drainage Issues: This is the most challenging aspect.
- Maintaining proper slope: Toilet drain lines require a specific downward slope (usually 1/4 inch per foot) to ensure waste flows correctly. Changing the location significantly might necessitate altering floor joists or even raising the floor level to achieve the correct slope.
- Venting: Toilets need proper venting to allow air into the drain line, preventing a vacuum that could siphon water out of the bowl. Moving a toilet may require extending or adding to the existing vent system, which often involves working within walls and ceilings.
- Drain Size: The drain line must be the correct size (typically 3 or 4 inches) to handle toilet waste. Any alteration must maintain this diameter.
-
Water Supply: Moving the water supply line is generally easier than dealing with the drain, but still requires careful planning and execution.
- Access: You'll need access to the existing water supply line, typically by cutting into the wall.
- Running the new line: You'll need to run a new water line to the relocated toilet, using appropriate fittings and materials (usually copper or PEX).
- Shut-off valve: Installing a shut-off valve near the toilet is essential for future repairs.
-
Floor Type: Working with concrete slab floors is significantly more difficult than working with wooden subfloors because it requires cutting into the concrete for drainage changes.
-
Your DIY Skills: Plumbing experience is crucial. Incorrectly installed drain lines can lead to leaks, clogs, and unsanitary conditions. Improper water supply connections can cause leaks and water damage.
Difficulty Level Based on the Scale of the Move:
| Scale of Move | Difficulty Level | Key Tasks |
|---|---|---|
| Slight Adjustment (inches) | Easy to Medium | Possibly extending the wax ring flange, minimal water supply adjustments. |
| Within the Existing Bathroom | Medium to Hard | Rerouting drain and water lines, potentially involving cutting into walls/floors. |
| To a New Location | Very Hard | Major plumbing changes, requiring significant structural alterations, permits, and possibly professional assistance. |
When to Call a Professional:
- Any time you're unsure about your abilities.
- When dealing with concrete slab floors.
- When major drainage changes are required.
- If you need to alter structural elements of your home.
- If permits are required in your area.
In conclusion, moving a toilet ranges from a manageable DIY task to a complex project demanding professional expertise. The key factor is the extent of plumbing modifications required, particularly concerning the drain line.
