If you have a large home with plenty of rooms, you might wish to turn a spare room into anything other than a guest bedroom.

You may change a room for roughly $500 by simply swapping out furniture, or your improvements could be much more extensive and cost upwards of $10,000. We’ve broken down how much it will cost to turn your bedroom into a home theatre, kids’ playroom, or home gym.

Home Cinema

Is there anything better than watching a movie while curled up on the couch with a bowl of popcorn? Consider transforming a bedroom into a home theatre to enhance this already fantastic experience. For some, this may imply rows of reclining seats, a popcorn machine, and a wall-sized screen; for others, it may imply surround sound and a comfortable couch. The cost of your home theatre will, of course, be determined by where you fall on the spectrum.

Basic home theatre packages with speakers, a subwoofer, and a receiver can cost around $475. For a wireless system with larger speakers and a more advanced receiver, more expensive packages can cost up to $2,500.

You’ll also need a television or a theatre projector in addition to the home theatre package. A projector might cost anything from $500 to $4,500. Depending on the size of the screen, a Smart TV that allows you to view Netflix and YouTube would cost between $400 and $2,700.

Of course, there are additional aspects to consider, such as soundproofing, if you want to take your home theatre to the next level. Acoustic sound batts can cost roughly $80 for 3.6m2, and acoustic foam can cost around $825 for a 5-metre length.

You’ll also need to invest in suitable lighting, furnishings, and floor coverings if you want to offer your guests the entire theatre experience. Comfortable seats and dimmer switch lighting are very significant in a theatre setting. Calculate how many people will be at the theatre at any given time and make plans accordingly. A huge L-shaped sofa or rows of individual chairs are both options. You should also close the window using blackout curtains to provide complete darkness during movie time.

A home theatre is an excellent place to spend quality time with family while watching a movie. The cost will vary depending on how lavish or basic your room designs are, but it will typically cost between $500 and $10,000. For a detailed Home Theater Cost Guide, go here.

Children’s Playroom

All parents understand the value of playtime in their children’s lives. Memories are formed, imaginations run wild, and mistakes are unavoidable. It’s time to turn that extra bedroom into the playroom of your child’s dreams if you want to win Parent of the Year.

Depending on your designs, an in-home playroom can cost a few hundred dollars or a few thousand dollars. If you really want to go all out, consider an indoor playground. An skilled carpenter can help you design a personalised playground with swings, slides, climbing towers, and other features that are specific to your space.

You’ll want to make sure this room is child-safe no matter how ornate you make it. Rubber floors cost between $30 and $80 per square metre when installed over existing flooring. If your children are rowdy, you may want to consider padding the walls as well.

Home Gym

Depending on the style of club and location, a weekly gym membership might cost anywhere from $15 to $150. Gyms are not only expensive, but they can also be inconvenient. Fitting a workout into a hectic schedule is difficult enough; add a commute and the chances of it happening are even lower. If staying in shape is important to you, turn that spare bedroom into a home gym.

The cost will vary, as with anything, depending on how extensive and high-quality your plans for the area are. Will you go all out with new flooring, lighting, high-end equipment, and floor-to-ceiling mirrors, or will you keep it simple?

We recommend investing in sufficient lighting if you know you’ll be using this room effectively. LED downlighting is recommended by experts. Some electricians charge up to $100 for each downlight. Proper lighting may transform the atmosphere of your area and perhaps make you feel more energised.

Rubber flooring is another important upgrade to consider. If desired, you can lay this over your current flooring. Rubber tiles that are 10mm thick and interlocking are recommended. Tiles range in price from $30 to $80 per square metre. This will assist protect your floor when working with weights and big equipment. Rubber flooring is also healthier for your body because it absorbs shock.

It’s rare to walk into a gym without seeing at least one wall of full-length mirrors. Mirrors in your home gym will help you monitor your posture and ensure that you’re exercising properly. A single relocatable 1200mm x 1800mm gym mirror module costs around $450 and comes ready to hang.

The most major potential drain on your budget is equipment. A yoga mat and a few bands will set you back about a hundred dollars, but a rack, bench, infrared sauna, cardio machines, and other equipment will set you back several thousand dollars.
