What are some Factors Influencing Bathroom Additions?
The main factors that will influence the costs and success of bathroom additions are:
- Location – if the new bathroom will be situated near existing plumbing then the process is easier to complete. This is because the further away the new bathroom is, means the more vents, sewage lines, drainage and plumbing lines needing to be installed.
- Size – the size of the new bathroom will determine multiple factors. Walls might need to be knocked down or added to how many tiles and materials are needed. The layout of the bathroom will need to be planned ahead to ensure that the bathroom is not too cluttered.
- Scale or Use – if the bathroom is for luxury or general use to be located near the master bedroom then this will influence the process.
- Age of Home – the older the home means that the likelihood of older plumbing and electrical systems are present. These will often need to be worked on or replaced with newer systems to facilitate modern needs.
- Electrical Work – powerpoints, lights, outlets and other electrical systems will need to be installed in most bathrooms.
- Plumbing Work – new piping systems and drainage lines will need to be installed within the new bathroom.
- Flooring – vinyl sheets, ceramic, laminate and many more flooring options need to be considered during bathroom additions.
- Ventilation – it is important that the bathroom is correctly ventilated especially with showers and baths included. An exterior wall with a window or a fan should be added to assist with air circulation.
Where Can I Add the New Bathroom?
A bathroom can be added almost anywhere but adding a new bathroom and its location should be considered carefully. A small bathroom can be as little as 1.5×2 metres where larger bathrooms are often 3.2×3 metres. The most common places where people will install new bathrooms are:
- Old Bedrooms – if a spare bedroom rarely is used often it is transformed into a bathroom. The space might also be larger so an additional bathroom that is larger might be favoured.
- Replacing Walk in Wardrobe – if the space of a walk in wardrobe is too big or it is not needed an en suite can be installed.
- Extension – if a new storey or an extension to the home has been developed a new bathroom is often considered to fill up the space.
- Laundry – from installing a toilet to adding a whole bathroom within or near the laundry often occurs. This is because plumbing is already present, such as from the washing machine, so installing fixtures to a new bathroom is not as difficult.
Half Bathroom or Full Bathroom?
A half bathroom often only has a sink and a toilet where a full bathroom has these with a shower and maybe a tub. Full bathrooms are commonly used for master bedroom bathrooms and also for the main bathroom. Half bathrooms are usually installed for a guest toilet, small en suite or to add an additional toilet. Knowing which one is needed will be useful to decide what to plan for the bathroom addition.
