This is what a buyer checks before they shortlist construction and building products suppliers.
What does a buyer check before specifying sanitaryware?
They check water consumption against the building's requirement, compliance with the market's sanitaryware standard, and rough-in dimensions against the existing plumbing. In refurbishment, which is most of the market, rough-in compatibility decides more purchases than appearance does, because moving pipework is the expensive part of the job.
A facilities buyer is replacing fittings in an occupied building without moving any plumbing.

First, what the product is
The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Product type and installation method
Wall-hung, floor-mounted and back-to-wall change the installation.
- 2
Water consumption per use
Regulated and increasingly specified.
- 3
Rough-in dimensions
Decides whether it fits existing plumbing.
- 4
Standards compliance
Determines legality and acceptance.
- 5
Material and glaze specification
Governs durability and cleaning.
- 6
Fitting and cistern compatibility
Determines spare parts availability.
- 7
Accessibility compliance
Required in public and commercial buildings.
Then the paperwork
Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Standards conformity certificateAsked at: specification and import | Conformity with the sanitaryware standard for the market | Publish it |
| Water consumption test dataAsked at: regulated specification | Flush volume and performance under a named method | Publish it |
| Flush performance test reportAsked at: commercial specification | Waste removal performance, not just water volume | Name it, share on request |
| Rough-in and dimension drawingsAsked at: installation planning — decisive in refurbishment | Fixing points and connection positions | Publish it |
| Accessibility compliance statementAsked at: public buildings | Conformity with accessibility requirements where applicable | Publish it |
| Spare parts availabilityAsked at: life-cycle assessment | Cartridges, seals and cistern parts, with availability period | Publish it |
| Warranty termsAsked at: purchase | Coverage for ceramic, fittings and mechanisms separately | Publish it |
The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.
The buyer asks: What does a buyer check before specifying sanitaryware?

A supplier with Standards conformity certificate on the page
Conformity with the sanitaryware standard for the market
A supplier with Water consumption test data on the page
Flush volume and performance under a named method
A supplier with Rough-in and dimension drawings on the page
Fixing points and connection positions

Questions suppliers ask
Why publish rough-in dimensions prominently?
Because refurbishment is most of the market and moving plumbing is the expensive part. A buyer who can confirm your product fits existing connections will choose it over a better-looking one that requires builders' work.
How should water performance be presented?
Volume per flush alongside waste removal performance under a named test method, because a low-volume product that needs two flushes saves nothing and generates complaints. Commercial specifiers understand this distinction well and are looking for evidence of both, so publishing only the headline water figure reads as an attempt to avoid the second question.
What matters most to facilities buyers?
Spare parts over a long life. Ceramic outlasts its mechanisms by decades, and a facilities team is judged on keeping fittings working. Publishing a parts availability commitment and a parts list is worth more to them than any appearance argument.
