Bathroom worktops and stone vanity tops cut to size in quartz, granite, Dekton or other sintered stone, from £110/m² (stone only), in the narrower widths a bathroom takes, with shelves and window returns to match. We seat and seal the basin, a plumber connects it.
A vanity top is short, and that is the whole difficulty. A basin, one or two tap holes, a splash return and often a window reveal all land within a few hundred millimetres of each other, and there is nowhere to move any of them to. On a kitchen run you can slide a join or a socket along a metre of stone. On a vanity you cannot.
The width is the constraint rather than the length. Standard vanity depths are far narrower than a kitchen worktop, which can work in your favour: a top can be cut from offcut stock where a piece suits, and then a material you were told was out of budget across a kitchen may be affordable across one basin. It also means the choice depends on what is on the rack rather than on a full slab order.
One division to be clear about. We seat and seal the basin into the stone. A plumber connects the water and the waste, and should be booked after us rather than alongside us, because the silicone needs to cure before the basin takes water.
Fitted 5–10 working days from template. The payment stages are set out on your quote.
Stone vanity tops
Any surface we supply can be cut down to a vanity. Supply rates are read from our catalogue and cover the stone only; the basin aperture, tap holes, edges and fitting are quoted as their own lines.
| Material | Colours | Supply from | On a vanity |
|---|---|---|---|
| Quartz | 69 | £130/m² | Most bathrooms: no sealing, consistent colour, and copes with water standing on it. Strong cleaners and cosmetics are wiped off rather than left. |
| Granite | 45 | £121/m² | A natural-stone vanity. Porous, so it is sealed before use and resealed periodically, which matters more in a bathroom than a kitchen. |
| Dekton | 63 | £110/m² | No sealing, and resistant to the cleaning products and cosmetics a vanity collects. Thin formats suit a slim floating top. |
| Sintered stone | 8 | £280/m² | Our own sintered stone range: no sealing, and unbothered by water, cleaners or cosmetics left standing. |
Free samples are posted from the Worktop Worx quartz collection, up to four at a time. Other quartz, granite and sintered stone are judged from the slab.
What is involved
The same stages as a kitchen, run across a much smaller piece, which changes what matters at each one.
Not the style, the actual products. An undermount basin is machined to its own template and a tap is drilled to the spacing it needs. Both are settled before anything is cut, because a change afterwards means a new piece rather than an adjustment.
At vanity depths a top can come out of offcut stock where a piece suits, so the honest question is what we have rather than what is in the brochure. It widens the choice at the expensive end of the range and narrows it at the plain end.
The vanity unit has to be fitted, fixed and level first. A short piece has no slack in it, and a few millimetres of movement in the carcass shows on a top this size in a way it never would across a kitchen.
The aperture is cut, an undermount basin is bonded and supported from beneath, and the cut edge is polished, because on a vanity you look straight down into it. Tap holes are drilled to the tap that is on site.
The top is scribed to the wall, bedded, sealed along the wall junction and cleaned down. Your plumber connects afterwards, once the sealant has had time to cure.
The awkward parts
Bathrooms are small rooms full of fixed obstacles, and the stone has to work around every one of them.
An undermount basin is bonded under the stone and the aperture is polished, because that cut edge is visible from above every time the basin is used. An inset basin drops in from the top and covers the same edge. They are different pieces of work and they are priced differently.
There is no standard spacing worth machining to. A three-hole set, a single monobloc and a wall-mounted spout that needs nothing drilled at all are three different tops, and the decision has to be final before the piece is cut.
Where a window sits above the basin, a stone reveal, a sill or a splash return off the vanity top can be cut from the same material and templated in the same visit, which is the only way the colour and the pattern carry across.
A vanity is small enough to come out of remnant material, which puts expensive stone within reach. It also means the exact piece is finite. If you want a matching shelf or window board, order them together while the offcut is still on the rack.
A bathroom top gets splashed constantly and wiped down rarely. Quartz and sintered stone need no sealing. Granite does, and it wants resealing periodically. Cosmetics, toothpaste and anything acidic are harder on a vanity than cooking ever is on a kitchen.
The same division of work as a kitchen sink. We bond, support and seal the basin into the stone. Supply, waste and any pop-up mechanism belong to a plumber, booked after us so the sealant has cured before the basin is loaded.
Vanity unit worktops
A new stone top can go on the vanity unit you already have, as long as the unit is sound. It is the same logic as replacing a kitchen worktop without replacing the kitchen: the unit stays, only the surface changes, and the unit has to be fixed, level and strong enough to carry stone. A wall-hung unit puts the whole weight into the wall rather than the floor, so what the wall is built of stops being a detail.
We template off the fitted unit, never off a plan, because a short piece has no slack in it and a few millimetres of movement in the carcass shows on a top this size. If the unit itself is being changed, fit the new one first and we template once it is in.
Before you order
A vanity involves fewer decisions than a kitchen, and each one is harder to undo.
Questions
If yours is not here, ring and ask. You will get a straight answer rather than a call-back from a salesperson.
Yes, and it is cut to the unit as it stands rather than to a drawing. The vanity unit is fitted, fixed and level first, then we template it on site with the basin and the tap there, so the aperture and the tap holes are set out from the real objects. The top is cut, bonded and polished in our workshop and fitted afterwards.
Yes. A vanity is priced as its own piece rather than as a length of worktop, templated, cut and fitted by us like any other job, and at vanity depths it can be cut from offcut stock where a piece suits. What we do not do is sell stone for somebody else to fit. If a kitchen is being done as well, ordering the two together puts both on the same slab run.
Usually, and it is worth asking early. Ordered together, both come off the same slab run and the match is real. Ordered a year apart, engineered stone will have moved batch and granite will be a different slab, so the two read as related rather than identical. In separate rooms that is normally fine.
Per square metre it is the same stone at the same supply rate, £110 to £550 depending on the range. The piece is simply much smaller: a vanity top 1.2m wide and 0.5m deep is 0.6m², so at the quartz entry rate of £130/m² the stone is about £78 before fabrication and fitting. At vanity depths it can often come out of offcut stock, so a material that would be expensive across a kitchen can be affordable across one basin.
Quartz for most bathrooms, because it needs no sealing and water standing on it does it no harm. Sintered stone if you want a slim top or the most resistance to cleaners and cosmetics. Granite if you want natural stone, accepting that a bathroom is where its sealing matters most.
Undermount looks cleaner and lets you wipe straight into the bowl, and the cut edge is polished because you look down onto it. Inset drops in from above and hides that edge, which makes it more forgiving and usually cheaper. Both are fine. The choice has to be made before the top is machined.
It depends on the material rather than the room. Quartz and sintered stone need no sealing. Granite does, and in a bathroom it is worth staying on top of, because cosmetics and cleaning products tend to sit on a vanity long before anyone wipes them off.

The questions that come up most, answered in full rather than in a sentence.
A stone vanity top is cut from the same slabs as a kitchen worktop, in a narrower width, and quartz is the easy choice for a bathroom because it never needs sealing. The top is cut for the basin and tap you bought, and a plumber connects them afterwards.

Read the guideClean a quartz worktop with warm water, a little washing-up liquid and a soft cloth, then dry it. For a deeper clean use a pH-neutral stone cleaner. Avoid bleach left standing, oven cleaner, abrasive pads and heat, because the resin in quartz is what they damage.
Read the guideThe best stone for an internal window sill is usually the one your worktop is made of, cut from the same batch at the same template visit. Quartz suits most kitchens and bathrooms, granite suits a sill you will seal, and a notched sill sits neatly inside the reveal.
Read the guideWhat each sink type does to the worktop it sits in: how the cut-out is cut and finished, what it costs in fabrication, what carries the weight, and why the sink has to be in your kitchen before anyone can template.
