If you’re renovating your bathroom or dealing with a broken spout, you may be wondering: can you use a shower faucet without the tub spout? The answer depends on your plumbing setup. In many cases, yes—you can use a shower-only configuration without a tub spout. However, if your current system was designed with a tub spout diverter, removing it without proper modifications can cause leaks, pressure problems, and wasted water.
How a Tub Spout Works
In a typical tub-and-shower combo, the water flows like this:
- When you turn on the faucet, water flows through the tub spout by default.
- Pulling up the diverter on the spout redirects water upward to the showerhead.
- The tub spout acts as the control point for whether water goes to the tub or the shower.
Without a tub spout (or another diverter system), the water has no way to switch from tub to shower.
When You Can Use a Shower Faucet Without the Tub Spout
You can eliminate the tub spout if:
- You’re converting to a shower-only system.
- Your shower faucet has a built-in diverter (common in single-handle shower valves).
- You cap or properly redirect the plumbing line that used to feed the tub spout.
In these cases, the shower will work fine without a tub spout, as long as the plumbing is modified correctly.
When You Cannot Simply Remove the Tub Spout
You cannot just take off the spout and leave the pipe open. Problems include:
- Constant leaks: Water will flow from the open pipe whenever you use the shower.
- Poor shower pressure: Water may still try to escape through the tub spout line instead of going fully to the showerhead.
- Plumbing strain: Uncapped or incorrectly capped pipes can create stress in the system.
- Building code issues: Some codes require a tub spout if a tub is present.
Options for Going Tub-Spout-Free
1. Convert to a Shower-Only Valve
Install a shower-only mixing valve that directs water straight to the showerhead, eliminating the need for a spout.
2. Use a Valve with Built-in Diverter
Some single-handle shower valves include a diverter switch or knob. This lets you control water flow to multiple outlets (like a showerhead and handheld sprayer) without a tub spout.
3. Cap the Tub Spout Pipe
If you remove the tub spout, the supply pipe must be capped off securely to prevent leaks. Use a threaded cap or soldered fitting for a permanent seal.
Tools and Materials Needed
- Adjustable wrench
- Pipe cap or plug
- Teflon tape or pipe sealant
- Silicone caulk (if patching wall after spout removal)
- Replacement shower valve (if upgrading)
Cost Considerations
- Pipe cap and materials: ₦5,000–₦15,000 ($10–$25 internationally).
- Shower-only valve replacement: ₦40,000–₦100,000 ($100–$250 internationally).
- Professional plumber service: ₦20,000–₦60,000 ($80–$200 in the US).
Pros and Cons of Using a Shower Without a Tub Spout
Pros:
- Cleaner look—no bulky spout under the shower.
- Ideal for walk-in showers or tub-to-shower conversions.
- Reduces wear and tear on diverter spouts, which are common failure points.
Cons:
- Not suitable if you want to keep using the tub.
- Requires plumbing modification to prevent leaks.
- May affect home resale if buyers expect a tub in a bathroom.
FAQs
1. Can I just block the tub spout opening?
No. You need to cap the plumbing pipe properly inside the wall. Blocking the spout externally won’t stop water from leaking inside.
2. Will my shower work better without the tub spout?
If you convert to a shower-only system, yes—more water pressure will go to the showerhead since it no longer splits with the tub spout.
3. Can I keep my tub but remove the spout?
No. If you want to use the tub, you must keep a functioning spout. Without it, you have no way to fill the tub.
4. Do I need a plumber to remove the tub spout?
If you’re comfortable capping pipes and sealing plumbing connections, you can DIY. For valve replacements or hidden pipework, a plumber is recommended.
5. Will removing the tub spout save water?
Yes, if the spout diverter was leaking, eliminating it ensures all water goes to the showerhead instead of dripping into the tub.
Conclusion
So, can you use a shower faucet without the tub spout? Yes, but only if you modify your plumbing correctly. If you’re converting to a shower-only setup, you’ll need a shower-only valve or a securely capped tub line. If you still want to use the tub, the spout must remain. Done properly, removing the tub spout can give your shower a cleaner look and better water pressure, but it’s important to handle the plumbing adjustments carefully or hire a professional plumber.
