Smart Toilet Buying Guide for Distributors

If you sell bathroom products in the United States, adding smart toilets to your assortment used to mean committing to a container, waiting through a production run, and hoping the rough-in matched. That changed. You can now order one unit, at factory wholesale pricing, shipped from a US warehouse — and build your range from actual customer demand instead of a minimum-order spreadsheet.

This guide walks through every decision a bathroom distributor needs to make before placing a first smart toilet order: voltage, rough-in, certifications, logistics, and the sourcing model that makes sense for your business.

Start with the two questions that cause the most returns

Before you compare features or negotiate pricing, pin down two technical details that drive the majority of B2B returns and installer callbacks.

1. What voltage does your market use?

North American bathrooms run on 110–120V. Not every smart toilet on the market is configured for that.

Of the eleven models in the Lavilys range, eight have a documented 110–130V, 50/60Hz configuration with US plug types. The remaining three are configuration-dependent — their voltage is confirmed in writing before quotation, not assumed from a catalog photo.

For a distributor, the practical takeaway is straightforward: shortlist the models that are already documented for your voltage, and treat “available in your market” as a question to verify rather than a feature to trust.

See the full voltage breakdown in the North American electrical requirements guide.

2. What rough-in does your customer’s bathroom have?

Rough-in — the distance from the finished wall to the center of the drain — is either 305 mm (12 inches) or 400 mm in most US bathrooms. Some models are fixed at one dimension. Others offer both.

In the Lavilys range, the A17 and A18 are fixed at 305 mm. The W1 and K1 ship as a 300 mm or 400 mm option. The 6293 is fixed at 300 mm.

The rule for distributors: before you quote, get the measurement. A rough-in mismatch is not something a plumber can adjust on site. If you are building a showroom assortment, stocking one model in each rough-in option covers the majority of walk-in customers.

Read the detailed measurement guide: choosing between 300 mm and 400 mm rough-in.

Certifications: what to ask for, what they actually cover

The word “certified” collapses four separate approval systems into one. For a US distributor, the four that matter are:

Certification	What it covers	What it does not cover
cUPC (IAPMO R&T)	Plumbing code compliance under the Uniform Plumbing Code	Electrical safety, water efficiency
UL (UL Solutions)	Electrical safety of the appliance under UL 1431/1951	Plumbing code, drain fit
WaterSense (EPA)	Water efficiency and flush performance	Product safety, electrical
FCC (Part 15)	Radio-frequency emissions from remotes and electronics	Everything above

A product can hold one and lack the others. When a customer specification says “cUPC certified,” they are asking about the plumbing inspector’s acceptance — not the electrical inspector’s, and not the water-efficiency label.

The most important procurement habit: read the model scope, not the logo. A cUPC listing covers specific model numbers, not an entire brand. Lavilys holds IAPMO file 11670 records, UL certificate UL-US-2232698-0 under file E527307, and FCC ID 2A558GC337894 — each scoped to identifiable models within the range. A certificate for one model is not evidence for its neighbor.

The sourcing model: why US warehouses change the MOQ equation

The traditional sourcing path for a bathroom distributor adding smart toilets looked like this:

Request quote → commit to a container MOQ → wait through production →
sea freight → customs clearance → warehouse receipt → start selling

That model assumed the distributor was importing directly. It required upfront capital, storage space, and a bet on which models would sell.

A warehouse-based model is different. When the supplier holds stock in US warehouses, the distributor’s first order can be a single showroom unit — shipped domestically, no customs, no port delays, no container commitment. Product validation happens in your store, with real customers, before you scale.

Lavilys operates two US warehouse locations:

Warehouse	Address	Contact
West Coast	17000 Gale Ave, City of Industry, CA 91745	Jessie · +1 (840) 244-5005
East Coast	543 Monmouth Rd, Jackson Township, NJ 08527	Giga · +1 (626) 912-8886

There is no minimum order. One unit, one pallet, or one container — factory wholesale pricing applies at every quantity. Replenishment orders ship from the nearest warehouse, which means faster restock and lower freight cost for your customers.

What to check in a product specification before you order

When you receive a specification sheet, here are the fields to verify — and why each one matters for your customer:

Spec	Why it matters
Voltage	110–130V for US; mismatch = unit won’t power on
Rough-in	305 mm vs 400 mm; mismatch = won’t fit the drain
Water pressure	Tankless models need 0.15 MPa minimum; low-pressure upper floors may need a tanked model
Dimensions	Confirm lid-open height and side clearance fit the bathroom
Flush volume	1.28 GPF or lower meets California and WaterSense thresholds
IP rating	IPX4 minimum for bathroom moisture exposure
Control type	Remote, side knob, or foot sensor — affects installation and user training
Warranty	2-year full unit on Lavilys models; quality defects covered, free replacement parts

A specification sheet that reads “confirm by configuration” on any of these fields means the supplier has not yet matched that model to your market. That is not necessarily a dealbreaker — but it means the configuration conversation needs to happen before pricing, not after.

What about retrofit? The bidet seat option

If your customer is renovating rather than building new, a bidet toilet seat is often the right call. It keeps the existing ceramic toilet in place and adds washing, heated seat, and warm-air drying functions.

The T1 and B04 are the two seat models in the range. The T1 is V-shaped, fits mounting-hole centers of 135–180 mm, and runs on a US-plug 110V configuration. The B04 is elongated, adjusts across 125–190 mm, and operates on 100–130V.

For either model, confirm three measurements before ordering: the distance from the mounting holes to the tank, the bowl length, and the distance to the nearest GFCI outlet. The bidet seat compatibility checklist walks through each one.

Warranty and after-sales: what to tell your customer

Lavilys provides a 2-year warranty on the complete unit. If a quality defect is confirmed — a material flaw or manufacturing issue, not improper installation or misuse — replacement parts ship at no charge.

The warranty process:

1. Report the issue with photos or video showing the fault and the model label.
2. Technical review confirms the cause — normally within 24 hours.
3. Replacement components are dispatched.

For after-sales support, your customer contacts you. You contact our team. The parts come from the warehouse closest to the installation.

Putting together your first order

A practical starting assortment for a bathroom showroom:

Use case	Model	Why
Premium integrated	A18	Auto lid, foot sensor, full comfort set — the flagship to show
Value integrated	A17	Same footprint as A18, fewer auto features — good/better pairing
Compact / tight spaces	W1	680 mm length, 300/400 mm rough-in — fits smaller bathrooms
Retrofit / renovation	T1	110V US plug, V-shaped — keeps the existing toilet

Order one of each as showroom units. Let customer response tell you which to stock deeper.
