Smart Toilet Installation in the US: What You Need to Know
Smart toilets are becoming a popular upgrade for many American households. Combining hygiene, comfort, and technology, they are an essential part of a high-end bathroom renovation. However, many buyers hesitate, wondering “Can I install this at home?”, “Is it compatible with US wiring and plumbing?”, or “Who should I hire to install it?”
This article walks you through the 5 key things you must know before installing a smart toilet in the U.S. Plus, we’ll introduce several models designed specifically for American homes so you can buy with confidence, install smoothly, and enjoy worry-free use.
1. Power Supply: What if there’s no outlet near your toilet?
Nearly all smart toilets require electricity to power heated seats, warm water washing, drying, night lights, and digital displays. But many American homes—especially those built before 2000—do not have an electrical outlet near the toilet.
✅ How to fix this:
- Check if there is a GFCI outlet (ground-fault circuit interrupter) near your toilet.
- If not, a licensed electrician can install one, usually costing between $150 and $300.
- If remodeling, have your contractor pre-install an outlet behind or beside the toilet area for neatness and safety.
Note: Never use extension cords for smart toilets—they’re unsafe and violate electrical codes.
2. Rough-in Size: Not every home has the standard 12-inch distance
The standard toilet rough-in in the U.S. is 12 inches—the distance from the finished wall to the center of the floor bolts. However, many older homes have 10-inch or 14-inch rough-ins.
✅ How to fix this:
- Measure the distance from your finished wall to the center of the floor bolts under your existing toilet.
- If it’s not 12", some models won’t fit without modification.
- You can use an offset flange or select a model that supports adjustable rough-ins.
- Many modern smart toilets fit only standard 12-inch rough-ins—be sure to verify before buying.
3. Water Supply and Pressure: Don’t overlook these details
U.S. water supply lines generally use 3/8 inch compression fittings. Some imported smart toilets use metric fittings and won’t connect directly. Also, some homes have low water pressure, which affects flushing performance.
✅ How to fix this:
- Choose US-market models that include standard American fittings out of the box.
- If your home has low water pressure, pick models with built-in booster pumps for reliable flushing.
- Our CASTA DIVA models come equipped with US-standard fittings and pump-assisted flush systems.
4. Wall-Mount vs. Floor-Mount: Wall-hung toilets aren’t common in the U.S.
Wall-hung toilets require in-wall tanks and reinforced wall framing, which most American homes don’t have unless newly built or undergoing major renovation.
✅ How to fix this:
- Stick to floor-mounted smart toilets that install like regular toilets.
- CASTA DIVA’s U010 series features a built-in water tank and booster pump, no wall modifications needed.
5. Who installs it? DIY or professional help?
Smart toilets are heavier and more complex than standard ones, involving electrical wiring and water connections. DIY installation is usually not recommended.
✅ How to fix this:
- Hire a licensed plumber and electrician for safe, reliable installation.
- Use services like TaskRabbit, Thumbtack, or HomeAdvisor to find local professionals.
- CASTA DIVA offers detailed installation manuals, video tutorials, and tech support to assist installers.
