Slate Monolith SM121 Water Feature


Slate Monolith SM121 is a lumpy square piece with a fairly flat sloping top. This will create a slow pooling of water before cascading down over the stone. This feature will add an instant aged look to a garden, rather than waiting for nature take its course. Weathered obelisk stones like this are in high demand and increasingly difficult to source. Standing at 500mm tall, the subtle textures of real Welsh Slate are magnified on this beautiful medium garden ornament.

Medium Stone Monoliths are becoming increasingly difficult to source, and Slate Monolith SM121 is an excellent example of a striking piece to be included in a medium or large scale garden design. This imposing block of real Welsh Slate echoes the countries’ ancient forts such as Dolwyddelan Castle near Betws Y Coed and Pentre Ifan Burial Chamber in Pembrokeshire. This piece can be combined with our Large Reservoir Pack that includes a reservoir, hose, clip & pump to complete the water feature set up. 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 SM121 is made from genuine Welsh slate, sourced from a North Wales quarry and hand finished in the Welsh Slate Water Features Workshop in Southampton. Many customers like to use monoliths with a number of our garden accessories, including slate stepping stones, 20mm chippings and LED Lighting (available in the basket when purchasing a monolith).

Stone Monoliths are perfect as focal points in landscape designs, they add beautiful natural stone textures and when combined with the Large Reservoir Pack its possible to bring the vibes of Welsh waterfalls to your garden. Natural stone and water feature ideas help bring tranquility to an outdoor space, ideal for balancing harmony and increasing the potential for mindfulness in your garden.
