Why I Believe 18 Inch Interior Door is Necessary
As a homeowner, I have come to realize the importance of having an 18 inch interior door in my house. Initially, I didn’t pay much attention to the size of my interior doors and just went with the standard size available. However, after living in my house for a few years, I started to notice some limitations and inconveniences caused by the standard sized doors.
One of the main reasons why I believe an 18 inch interior door is necessary is for better accessibility. Standard sized doors are usually around 24-32 inches wide, which may seem like enough space for most people. But as someone who has family members with mobility issues, I realized that these doors can be quite narrow and make it difficult for them to move around freely. With an 18 inch door, it provides more room for individuals using walkers or wheelchairs to comfortably pass through without any barriers.
Moreover, having an 18 inch interior door also adds aesthetic value to the house. These doors are considered wider than the standard size and can make a room appear larger and more spacious. This was especially beneficial in my small home where every inch of space counts. The wider door created an illusion of more
My Buying Guide on ’18 Inch Interior Door’
As someone who has recently gone through the process of buying an 18 inch interior door, I understand the importance of finding the perfect one for your home. It can be overwhelming with so many options available in the market, but with this buying guide, I hope to make your decision-making process easier and more informed.
1. Measuring and Determining the Right Size
The first step in buying an 18 inch interior door is to measure the opening where you want to install it. This will help you determine if an 18 inch door is the right size or if you need a custom-sized door. Keep in mind that standard door sizes are usually slightly smaller than their stated measurements, so it’s always better to measure twice and confirm before making a purchase.
2. Material and Style
Interior doors come in a variety of materials such as wood, glass, and composite. Each material has its own advantages and disadvantages, so it’s important to consider your needs and preferences before making a decision. For example, wood doors are durable and offer good insulation, while glass doors allow for more natural light to flow through.
Similarly, there are various styles available like panel doors, French doors, and pocket doors. Choose a style that complements the overall aesthetic of your home.
3. Door Swing Direction
The direction in which your door swings open is another important factor to consider when buying an 18 inch interior door. This will depend on the layout of your room and furniture placement. Make sure to choose a swing direction that doesn’t block any pathways or interfere with furniture.
4. Hardware and Finishes
The hardware and finishes of your interior door can greatly impact its overall appearance as well as functionality. You can choose from a range of finishes like brushed nickel, bronze, or chrome for handles, hinges, and locks. Make sure they match with other hardware in your home for a cohesive look.
5. Budget
Budget is always an important consideration when making any purchase. While it’s tempting to go for cheaper options, keep in mind that an 18 inch interior door is not something you’ll be replacing frequently. Invest in a high-quality door that will last longer rather than compromising on quality for cost.
6. Research Brands and Reviews
Before finalizing a purchase from a specific brand or supplier, do some research on their reputation and read reviews from previous customers. This will give you an idea about their product quality as well as customer service experience.
7.Delivery Timeframe
If you need your interior door urgently or have specific timelines for installation purposes, make sure to check the delivery timeframe with the supplier before placing an order.
8.Installation Process
If you’re not hiring professionals for installation services, make sure to read through installation instructions provided by the manufacturer carefully before attempting it yourself.
I hope this buying guide helps you find the perfect 18 inch interior door for your home! Remember to take your time and consider all factors before making a decision.
