Slate Monolith SM37 is a tall, impressive piece of Welsh Slate standing at just over a metre high. This is a very clean stone with a flat top which will act as a bird table, encouraging wildlife to your garden. Used with our Large Reservoir Pack, the flat top and faces allow a nice even flow of water to cascade down, transforming the monolith into a large water feature. The subtle textures of real Welsh Slate are magnified on this beautiful piece, every side covered in unique natural stone detailing.

Large Reservoir Pack and LED Lighting available in the Basket.

Accessories for Welsh Slate Water Features




Large Stone Monoliths are becoming increasingly difficult to source, and Slate Monolith SM37 is an excellent example of a striking piece to be included in a medium or large scale garden design. This imposing garden obelisk of real Welsh slate is core drilled to allow for water flow, achieved in conjunction with our Large Accessory Pack that includes a reservoir, hose, clip & pump. Please refer to our How To Install a Water Feature guide for detailed installation information. Delivery is via trusted courier or by Ioan Raymond himself. Slate Monolith SM37 is made from 100% natural Welsh slate, sourced from a North Wales quarry and hand finished by Ioan Raymond in his Southampton Workshop.
