Bathroom Renovation — FAQ
What size shower head is best for a guest bathroom?
10-12 inches provides optimal coverage without overwhelming small spaces. Larger heads need higher water pressure. For standard 8-foot ceilings, 10-inch heads keep guests comfortably warm throughout the spray pattern.
Do these shower systems work with low water pressure?
Most require 40-60 PSI minimum. Systems with pressure-balancing valves perform better in low-pressure homes. Consider adding a booster pump if your PSI drops below 40, or choose a 10-inch head instead of 12-inch.
Can I install a shower system myself?
Wall-mounted units are DIY-friendly with basic plumbing skills and take 2-4 hours. Ceiling mounts and panels need overhead access—hire a pro if you can't reach plumbing through an attic or cut drywall confidently.
What's the difference between pressure balance and thermostatic valves?
Pressure balance maintains temperature during pressure drops (toilet flushes). Thermostatic maintains exact temperature regardless of pressure—better but pricier. Both protect guests from scalding, but thermostatic adds luxury precision.
What's the benefit of dual shower heads?
Dual heads let guests choose between rainfall and targeted spray, or couples can use both simultaneously. In practice, most diverters switch between heads, not both at once—still a versatile upgrade that adds perceived value.
How long do shower systems last?
Solid brass systems last 15-20 years with minimal maintenance. Plastic components fail within 5-7 years. Matte black finishes hold up 10+ years if cleaned properly. The valve is the critical component—brass internals are non-negotiable for longevity.
