This entire range can be made without castors. The tops are made out of SA Pine and are supplied stained and unsealed. They can be sealed with a sealer bought from any hardware or paint shop. We offer hardwood tops in Saligna or Ash. (Both these woods are from sustainable forests.) If you would prefer a top of your choice such as Granite, Caesar Stone, concrete or a different hardwood; we can supply units without tops at a discount. Should you decide to replace the tops at a later stage, they are easy to remove. Units can be custom made. All units are interchangeable and can be made in any range and in any of the four paint finishes.
