Common questions

Before you buy.

Which worktops suit an undermount sink?

Undermount sinks fit below the worktop for a seamless edge, so they suit solid timber, stone and solid surface worktops. Most laminate worktops need an inset sink instead.

Will this sink fit my cabinet?

Each model lists the cabinet size it needs. Check it against the width of your sink base unit before you order, or send us your sizes and we’ll check.

How much is delivery?

Sinks, taps and accessories from The 1810 Company are delivered for £10 + VAT anywhere on the UK mainland.

How quickly will it arrive?

In-stock sinks from The 1810 Company are dispatched the next working day when you order by 12 noon. Each model shows whether it is in stock, and if it isn’t we’ll confirm the delivery date when we check your order. Ordered with a kitchen, it travels with the rest of your order.
