The 10 Decorative Septic Tank Cover Ideas

1. Faux Decorative Rock

Materials: Recyclable materials, spray foam insulation, concrete or cement, paint
Tools: Wheelbarrow, trowel, cement mixer, rubber gloves, paintbrush
Difficulty Level: Easy

One of the simplest and most decorative ways to cover a septic tank is with a faux rock cover, and this tutorial shows you exactly how you can do it. Besides this project being a fun learning activity for working with cement, you can use recyclable materials such as plastic bottles to create the base for the insulating foam that forms the shape of the rock. It is durable and realistic and will complement your landscape while covering up your septic tank.


2. Raised Log Bed

Materials: Logs, PT boards, screws
Tools: Saw, hammer, plants
Difficulty Level: Easy

This raised log bed combines landscaping and carpentry to create an excellent decorative cover for your septic tank. You can easily adjust the plan to allow access to your septic tank’s lid when necessary. We suggest creating a movable centerpiece the size of your septic tank lid and focusing the garden on that. You can choose whichever plants you like that will work with your landscape design. However, succulents are always a great choice as they are low maintenance and don’t have invasive roots.


3. Round Raised Garden Bed

Materials: Round galvanized fire rings, enamel paint, steel wool, white vinegar
Tools: Paintbrush, compost, garden soil
Difficulty Level: Easy

Covering your septic tank with raised garden beds is a practical way to disguise it. Round galvanized fire rings are inexpensive and have no bottom to them, making them a great container for this project. You can paint them with any color and create a raised flower bed or container for growing other ornamental varieties.


4. Use Old Wine Barrels

Materials: Wine barrels
Tools: Saw
Difficulty Level: Easy

You can put old wine barrels to good use by using them to cover your septic tank. On their own, they are a decorative addition to the garden, or you can give them a coat of paint to personalize them, but you will need to cut a hole in the bottom so that your septic tank lid has access. You can also use a wine barrel to create a septic riser if your tank has problems such as freezing, and this tutorial will show you how. You can place plants or decorative garden items on the top to spruce it up.


5. Gravel, Pebbles, and Stones

Materials: Rocks, gravel, pebbles, decorative garden items, plastic
Tools: Shovel, rake, garden gloves
Difficulty Level: Easy

Another great way to disguise your septic tank is to create a feature with gravel, pebbles, flowers, and even a bird bath. You can use large rocks to frame the tank’s opening so that it has easy access, and you can even make your own rocks using this tutorial! You can really get creative with this idea, using various types and sizes of stones.


6. Trellis

Materials: Treated wood, screws, nails, concrete, wood glue, stain
Tools: Shovel, saw, nailer, measuring tape, level
Difficulty Level: Easy

A trellis is ideal for privacy and can double up as a cover for your septic tank. You can grow vines or creeping plants to add some greenery or color but be sure not to plant anything with invasive roots. Building a trellis is simple and is a perfect project for anyone looking for something easy to create.


7. Wishing Well

Materials: Treated lumber, plywood, long screws, carriage bolts, flathead nails, rope, bucket
Tools: Saw, hammer, drill, sander, level, measuring tape
Difficulty Level: Easy to difficult

A wishing well can hide your septic tank while adding some charm to your garden and is a great idea that kids will love. It is easy to construct, but because it is a cover for your septic tank, it won’t include water. You can stain the wood for an organic look or paint it in colors that suit your garden design. Also, you can plant some flowers around the well, as well as inside the bucket to help it blend into the rest of the garden.


8. Mosaic Lid

Materials: Mosaic tiles, adhesive, grout, sealant
Tools: Tile nippers, wire cutters, kitchen sharpener, sponge
Difficulty Level: Easy

Hiding your septic tank can be an opportunity to get creative, and whether you haven’t mosaiced before or are familiar with the art, you can easily add some mosaic art to your garden. You can mosaic the lid of your septic tank lid in a decorative way, along with some stepping stones of the same size to blend it in. Make sure it’s not seen as a walk path as you don’t want anyone stubbing their toe on the lid handle. If you are new to mosaicking, this guide will help you get started.


9. Pallet Wood Wall

Materials: Pallet wood, screws, sandpaper, stain or paint
Tools: Jigsaw, drill, sander, paintbrush, level, measuring tape
Difficulty Level: Easy

A decorative pallet wood wall is a great way to hide your septic tank, as well as protect it from foot traffic. You can get creative by painting the wall, adding hanging plants or plant holders, and installing lights and flowers. You can also opt for a rustic look if you like to keep things simple; either way, it will be a great addition to your garden.


10. Bird Bath

Materials: Plastic flowerpots and trays, Gorilla Glue
Tools: No tools required!
Difficulty Level: Easy

A bird bath is always a sweet addition to the garden, and this inexpensive bird bath project is a great way to cover your septic tank. All you need is a plastic flowerpot with a diameter that is slightly bigger than your septic tank lid, and the tray which will be used as the actual bath.
