More Info

Slate Monolith SM303 is a really striking piece, due to it’s varied natural colours and markings. Placing this Large Sized Monolith where it can be viewed from at least 180 degrees would be ideal, as all faces have interest and unique patina. Complete with moss on the edge to give it an aged and weathered feel.  Additional gallery images highlight just a few of the many beautiful natural colourations on this unique garden monolith. Please view our you tube channel for a short video on the water cascasing down the slate. A design tip would be to add a small number of lower level boulders or rockery pieces to ease the transition in height into the overall garden design. Combine Slate Monolith SM303 with our Large Reservoir Pack to complete the water functionality, available in the basket. Add a couple of bags of slate chippings or rounded smooth paddle stones around the base to hide the lid of the reservoir. An alternative to Slate Monolith SM303 Water Feature is Slate Monolith Water Feature SM302 Water Feature. Monoliths of this size and quality are becoming increasingly difficult to source from the quarry. We are doubtful to have any more in stock like this during this season. Gallery images show a number of different angles. Take a look at How to Install a Water Feature so you can plan your installation now. Please contact us with any queries or questions.

All our core drilled Stone Monoliths require additional products to complete the water feature functionality, namely a water reservoir, pump, hose and jubilee clips. Either integrate with an existing set up or ideally use our Large Reservoir Pack. Water is recycled through the reservoir and back to the top with the pump, so a constant water supply is not required. We recommend contracting a professional electrician to provide the outside mains power for the pump.
