The Real Cost of Owning a Smart Toilet in the US — Everything You Need to Know

by zhang Tina 07 Jul 2025 0 comments

Looking to upgrade your bathroom for more comfort and better hygiene? Smart toilets are becoming a popular choice among American households. But beyond the sticker price, many ask: “How much will it really cost? And is it worth it compared to a traditional toilet?”

Today, we break down all the real costs of buying, installing, using, and maintaining a smart toilet in the US — so you can confidently choose a high-quality brand like CASTA DIVA.

1️⃣ Purchase Price: Options for Every Budget

Smart toilets come in a wide price range, from basic to premium:

  • Entry-level: $500–$800
  • Mid-range: $900–$1,200
  • High-end: $1,200–$1,500

CASTA DIVA smart toilets cover this entire $500–$1,500 range, offering models from practical to luxurious:

  • $599 entry model with essential smart features
  • $899 popular mid-tier model with rich features
  • $1,399 top-tier with auto open/close lid, warm air dryer, digital display, boosted water pressure, foot sensor flush, and more

You don’t need to spend $3,000 to enjoy a fully featured smart toilet — that’s the value CASTA DIVA delivers.

2️⃣ Installation Costs: Easier Than You Think

Installation worries? Not so bad:

  • Direct replacement: If your plumbing and power are ready, you can install it yourself with little to no extra cost
  • Hiring a plumber/electrician: About $300 for professional, hassle-free installation
  • Adding power outlets or plumbing upgrades: Typically $500–$1,500+ for older homes

CASTA DIVA models are designed with US households in mind to simplify installation and cut labor costs.

3️⃣ Electricity Usage: Surprisingly Low

Smart toilets use electricity for:

  • Heated seats
  • Instant warm water
  • Night lights
  • Automatic deodorizing

On average, this adds about $2–$8 per month to your electric bill — cheaper than a couple of lattes. CASTA DIVA includes energy-saving modes to keep standby power use minimal.

4️⃣ Water Usage: Smarter and More Efficient Than Traditional Toilets

Worried about higher water bills? Think again:

Traditional Toilet CASTA DIVA Smart Toilet
Water per flush 1.6 gallons 1.28 gallons
Daily usage (20 flushes) 32 gallons 25.6 gallons
Daily savings 6.4 gallons
Annual savings 2,336 gallons

Assuming a family of four flushes 20 times daily, CASTA DIVA saves over 2,300 gallons per year — that’s more than 45 full bathtubs!

At an average US water rate of $5 per 1,000 gallons, that’s about $11–$12 saved annually — and even more in high-cost or drought-prone areas.

5️⃣ Maintenance: Lower Costs and Longer Intervals

  • Deodorizer filters: Most brands require replacement every 6–12 months, but CASTA DIVA filters last 5–10 years, cutting down frequent replacements and expenses.
  • Water filters: Typically checked or replaced every 3–5 years depending on water hardness.
  • Nozzle cleaning: CASTA DIVA features automatic nozzle cleaning to reduce manual maintenance.

That means almost no replacement costs or hassle for years.

6️⃣ Warranty and Repairs: Peace of Mind

  • Standard warranty: 1–3 years
  • Extended warranty: $100–$500

If repairs are needed after warranty:

  • Heated seat replacement: $200–$400
  • Control board repair/replacement: $200–$400
  • Nozzle assembly replacement: $50–$100

CASTA DIVA offers solid after-sales support and genuine parts in the US to keep you worry-free.

7️⃣ Medical Reimbursement and Tax Benefits: Worth Checking

If purchasing for seniors or people with mobility challenges, some costs might be reimbursed by insurance or qualify for tax deductions. Consult your accountant or insurer to learn more.

Why Choose CASTA DIVA?

Whether your budget is $500 or $1,500, CASTA DIVA has a smart toilet that fits your needs:

  • Great features at fair prices
  • Energy and water-efficient to save you money
  • Easy installation to reduce upfront costs
  • Sleek, modern design to enhance your bathroom
