This is what a buyer checks before they shortlist a construction and building products supplier.

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.

Every claim on a supplier site has a document behind it or it does not. Buyers in sanitaryware know which is which.

What a buyer needs to identify the product

These are the fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.

  1. 1

    Product type and installation method

    Wall-hung, floor-mounted and back-to-wall change the installation.

  2. 2

    Water consumption per use

    Regulated and increasingly specified.

  3. 3

    Rough-in dimensions

    Decides whether it fits existing plumbing.

  4. 4

    Standards compliance

    Determines legality and acceptance.

  5. 5

    Material and glaze specification

    Governs durability and cleaning.

  6. 6

    Fitting and cistern compatibility

    Determines spare parts availability.

  7. 7

    Accessibility compliance

    Required in public and commercial buildings.

The documents buyers ask for

Not all of them belong on a public page. Naming the ones you can issue is what separates a supplier who can be audited from one who cannot.

Where sanitaryware sites lose the enquiry

Each of these is common, cheap to fix, and costs an enquiry that never arrives — so nobody ever reports it.

  • Rough-in dimensions not published

    Most sanitaryware purchases are replacements. Without dimensions a buyer cannot tell whether it fits without moving plumbing, which is the whole cost question.

  • Water consumption not stated

    It is regulated in many markets and specified in most commercial projects. Its absence removes the product from those specifications.

  • Spare parts availability unaddressed

    Cartridges and seals fail long before the ceramic. A product whose parts vanish becomes a facilities liability, and experienced buyers check first.

What the enquiry form should ask

A form that collects these can be answered properly the first time. A form that collects a name and a message cannot.

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.

Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
