kitchen plinths

Depends on customers preference and availability limited colours in upvc and are not as rigid as wood plinths plus plastic plinths can be static and attract hair and fluff more so

Definitely wood. Plastic is not robust enough to withstand a long life as a plinth. The most common is chipboard wood with a veneer.

Customer preference ,i can tell them wood is rigid .plastic can be static and attract fluff more ,up to the customers ,both can bee fittet

I would always recommend a MFC plinth (chipboard same as kitchen). Would also use the raw edge to the underside of the units and use a plinth seal strip. Not very expensive but stops any water ingress.
